I have recently gotten back into shooting my Rem 700 .308. I bought this rifle many years ago with the intention of eventually updating. When I bought the rifle, I envisioned an aftermarket stock and cerakote. Remington's blued finish is ABSOLUTE CRAP!!! To the point where I would shoot the gun one afternoon and case it up. Then when shooting the next day (not even 24 hours later), there would be a sheen of rust. I mean it was easy to wipe off, but that's crap.
The original gun is a Remington 700 SPS Tactical AAC-SD with a Vortex Viper PST 4-16. I chose .308 because it was a popular/common caliber that was readily available commercially. I had "visions" of eventually getting into reloading. I enjoy shooting steel in general, so when the steel got taken down at KHSC I lost motivation to shoot the 700, as well as a lull in my shooting in general. Anyways, I have the bug again and have picked up the update.
As I've gotten back into shooting the 700 and started reloading, I've received a lot of feedback from folks on the forum and friends, as well as on the internet. I've found that like many things in life, context is key when receiving feedback. From folks that hunt, to are interested in stuff like PRS style/level shooting, and F-Class and benchrest folks. I'm somewhere in the middle. I mostly just want to improve on the stock gun and goal is better results than commercial match ammo. Not expecting to get into the 0.25 MOA average level, but of course want to get the best I can out of the gun, ammo, and my shooting ability.
Cutting to the chase, here's where the gun is at now:
- Cerakoted barrel, action, and bolt (with larger bolt knob)
- American Precision Arms Little Bastard brake, turned down to match the barrel OD
- MPA Competition chassis with side folder
- Nightforce ATACR with MIL-XT reticle with Spuhr mount and Seekins base
- Geissele Rem 700 Super trigger (likely going to change out soon)
- Atlas BT65 bipod
When the work was done to cerakote and install the brake was done, since the barrel and action had to be taken apart, I had the gunsmith perform some "cleaning up" of the action, chamber, and crown.
Pause here. . . why not just go with a custom action and barrel? Yup, I would have if it wasn't for a few things. I wasn't expecting to go that far with the updates and I wanted to get the gun back shooting soonest. The actions I was looking at were pretty long lead times. Add to that the registration "situation". Current plan is to shoot this action/barrel a lot and see how the reloading goes and then decide where to go from there.
I got the gun back end of Dec and was able to fit in a range day to zero the gun and a "fun" range day. Zeroing on the first range day was pretty quick. I think I took about 3 rounds to get pretty close. I have a useful reference point on a building next door that allowed a pretty good boresight at about 125 yards. Wish I had done that on previous rifles. I was able to shoot a few 5 shot groups that first range day and was pleased with the results with factory ammo.
Then on the "fun" range day, I was able to get pretty good chrono data for the FGMM. Good to set a baseline for many things moving forward, both for shooting the gun in longer ranges and reloading. With the chrono data and ballistic app, I was able to get decent first round hits on steel in the 300 yard to mid 400 yard range, so I was quite happy. By decent, I mean with help from "a friend" on the wind call, first round hits on steel near the center of the plate. The group had a laugh when I had the first round hit on the first target and I was like "I hope that wasn't a one hit wonder" ;D
So now that I'm somewhat comfortable with the gun setup, focus is shifting to reloading. I have 100 rounds loaded up from my first batch of loading. I have decided to go a different route with the load development, but it will be interesting to shoot the rounds that I have loaded up.
It's been a fun process so far. Learning a lot and have had a few mistakes in ordering components that weren't "quite right". I think I've gotten past that with the gun, but will likely have more of that with the reloading components. As I've mention in other threads, I like to try different things and see for myself. I've gone through the growing pains with handguns and ARs, and starting down that road now with bolt action rifles. A bit of bad timing as many of the reloading components are tougher to come by.
Haven't been this excited about shooting in a while. Just wish we had more diverse ranges to shoot at. This might make me look into joining SRGC again. Will see. . .

One thing about SRGC though..... there is a 12 Hour volunteer requirement per year and if you can’t you either have to pay $100 plus the $40 for membership. They normally do not post any requests for volunteers on their website and when they do it’s normally the evening before or the morning of. What a joke. All last year I asked to have an area on their website that members could check to see what needs to be done and sign up. Never happened. Decided it wasn’t worth it anymore and as of 1 Jan 21 my membership expired. Nice way for them to treat vets and active duty....

Nice!Ya. Sounds same when I stopped my membership, maybe 4-5 years ago. At that time, I was volunteering as RSO. For at least a couple of years, I had way more volunteer hours than I shot. Then they started this “rule”. Pissed me off. I used to help clean up other areas that I didn’t even utilize, like the shotgun range.

I haven't been to SRGC in a long time. I got put off by their new requirements and other things. There's been problems with the volunteer system when I first joined 20 years ago, it just seems so disorganized in that regards. Posting it on the website is a good idea.

Getting little older and out of shape and wasn’t fun anymore like my younger days.
Down calibered to a .243 Weatherby and loving it again.
Love working the bolt deliberately.
Never stretched it but more accurate than I am at 100.
Never did shoot a .308.
Sounds like you got a nice set up Drck.

I got a Remington 700 in 3006. I was contemplating changing the stock and trigger and reloading rounds for it, but I don't expect to have the time to shoot it much so I kept it stock and shoot factory rounds. I'd like to take a precision rifle class somewhere someday. If I bring a group to the range I just shoot surplus Greek HXP out of it, though it's difficult to extract the brass after firing for some reason. I haven't had any rusting problems on this or other blued Remingtons. I keep them oiled up with CLP to prevent rust.Is your Rem 700 in the trigger recall? Mine was. I changed out to the Geissele, but now I'm thinking of going with Triggertech. The Geissele is much better than the stock Rem trigger, but there are some things I have noticed about it that I don't care for.

I had planned on taking a precision rifle class with my LPVO, but then COVID hit. Now, I'm thinking of a class with the same instructor for the bolt action. He does a lot of long(er) range courses. Of course, open to others as well.
Sold my .30-06.Thanks. .308 is good in that it's very common and lots of experience folks can share on setups as well as reloading. I was a bit impatient and should have waited until my scope came in and gun came back to decide on the optic mount and base. But with the extensive info online, I was pretty sure on what I ordered and it worked out to be perfect fits.

Shot some factory ammo to confirm chrono was setup properly ahead of the load testing. Also took some time to confirm zero, scope level, etc. The 5 shot group with FGMM 168 gr was pretty good, so at least I had a good baseline to how I was shooting prior to the load tests.
Some highlights:
1) Magnetospeed chrono was awesome. Super easy to use once it's setup. The Labradar is probably easier overall to setup and use, but the Magnetospeed was a good alternative, particularly for the setup "limitations" of Koko Head (and not needing a tripod). I have a mount for the Magnetospeed that attaches to the chassis/stock than the barrel. It's easy to setup, but have to be sure the bayonet location is just right. That's where I think the Labradar is easier to use. The chrono data for the FGMM 168 gr from the Magnetospeed was consistent with the Labradar data from last weekend, so that was good confirmation.
2) My chassis has a rail on the bottom that can adjust the position of the bipod along the rail. That is really helpful. It allows more options for shooting in varying positions, not just prone.
3) Load testing went well. I was mostly interested in validating that my reloads were "ok". But that I mean functioned properly, no unusual things, etc. I was pleased that all rounds functioned properly and got some promising results on paper as well as chrono data. Gave me some good info for further refinement with the two powders I tested (4064 and Varget). I'll likely try at least one more powder before I decide which powder to isolate testing.
4) Shooting bolt action seemed very relaxing. I took half day off from work Friday afternoon, so left the office stuff behind. The range wasn't that crowded and overall nice day on the range. I now have a better idea of how many rounds of test loads to budget in terms of time on range. I had planned on shooting from 12 to 4 pm, but I was done at 230 pm.
Overall, encouraging start to my reloading process. Still a ways to go with the load development and "upping" our reloading process, including with upgrades on reloading equipment.

Shot my first batch of reloads. Will share more of that in the reloading section. Was a great day and pretty excited about further load development, as well as refining the loading process. Both for myself and my buddy who while has been reloading longer than I have, he's getting more into the precision aspect of reloading, than more "good enough".

Nothing new for the bolt gun itself. Finally have all the correct components and attachments, so getting used to the setup that I envisioned. That as opposed to having to figure out a way to make things work with what I ordered. The current setup is quite flexible in many aspects, which is what I wanted. I think I'm mostly getting used to how I set things up at home, like LoP, comb height, etc. Or at least I haven't felt the need to adjust. My previous bolt gun was fixed everything and I'm pretty sure I didn't set it up properly as I found that I was occasionally having to adjust for proper eye relief. With the current setup, I am able to get into a comfortable/natural position for shooting assuming somewhat usual shooting "space", so no muscle use or tension.
Mostly focusing in improving loading equipment (since I use a friend's shop and his reloading "base" equipment). I added a RCBS Chargemaster, which helped speed things up and allow more multi-tasking of loading operations. Next on the list are different case trimmer and annealer. Picked up dies that will allow me to set things up for my own gun and use the existing press. I will likely invest in my own press somewhere along the line as current bench space with presses will only allow one person to do the main loading operations at a time.
Some highlights:
1) The Magnetospeed continues to impress. Getting faster in setting things up and use of the equipment is super easy. Even downloading the data to my home laptop, which will be super helpful when the more serious load development starts.
2) I'll have to watch my consistency in loading operations. Not sure if it was me technique or the seating die had shifted. But I had loaded up some Varget for a range day coming up in the near future and I noticed that the initial rounds were at my planned seating depth and then later rounds were slightly longer. It was still well within safe parameters, but something I'll have to keep and eye on. Will check the seating die in my next loading session and be sure to concentrate on being more consistent. With this batch, with the powder thrower in full swing, the operation was much faster than I had been in the earlier loading sessions.
3) Load testing went ok. I got decent results from 8208, but was quite disappointed with the Shooters World. The SW did show some promise, so might still work with it some. Overall, all good data for the overall process.
4) It's interesting listening to different folks' theories and gun "knowledge" that they drop. My electronic hearing pro picks up a lot, and I mean a LOT. For example, I could clearly overhear a group was maybe 3-4 benches over. The initial group was a family, which were all nice (they came by to ask about my gun and we chatted), but then a couple guys joined them, one of them was quite "self knowledgeable". Anyways, the Magnetospeed is apparently for stabilization, like how compound bows have the arm in the front. He was also shooting .308, which was throwing the boolits at over 3100 fps :o . . . super impressive, eh. . . On the positive side, I was able to help a nice guy who was next to me sort out his hunting bolt gun after having POI shifts due to a recent change in muzzle device. Super cool guy and was good to talk bolt guns, even from different perspectives. It's that kinds of interactions at the range make it more fun.
5) The RSOs were asking all of the folks setting up if they were going to save their brass. They even brought out their own brass nets for those shooting semi-autos who said they weren't going to save the brass and that the RSOs could have them. I guess a sign of the times.
Anyways, more fun experiences with the bolt gun. Looking forward to more.

Was able to load up and shoot the next round of test loads last week, which included 8208 and Shooters World (just as good as Varget). I'll start a thread in the Reloading section for my test loads and results. Initial read is 8208 showed decent promise with Shooters World being mostly disappointing. However, still being new to reloading there are a few things I want to follow up on, particularly with equipment setup.

Cool update.
I think the RSOs should be focusing on more important matters such as watching shooters instead of picking up brass. That's why there are many "Stay behind the yellow line!" scoldings during a cease fire.
Post by: drck1000 on January 19, 2021, 09:55:50 AM
Cool update.Yup. I mean I generally believe most of them mean well and want to make sure folks enjoy shooting. But even during ceasefires, there are times when they don't pick up on things. When I go by myself, I want to be sure they are keeping an eye on the benches when I am either downrange or have to take a piss. In any case, I usually keep an eye on when shooters jump on the benches near me. Some just don't seem to understand "keep the muzzle down range at ALL times" means when you uncase it as well. . . :o

this past Saturday scooped up some 9mm brass from the silly side. noticed a couple shooters throwing their brass in the bin so I asked if I could have their brass and they said ok. so i'm more of a polite vulture :thumbsup:

This location has opportunity for shooting in the 200 to just over 1000 yard distances. The wind is particularly challenging because of the terrain and lack of indicators along the way. The wind is usually vastly different from the shooting positions to the target.
Some highlights:
1) Having a gun setup just right for you is key. Before the update, my bolt gun wasn't setup very well for me. The eye relief was setup based on things when I first got my bolt gun and I didn't adjust it as I shot and as well as improved, or refined my shooting. I recall the initial session at this location, I found myself fighting the gun and to get a clear sight picture. I think that was mostly due to poor comb height, but also eye relief. With the gun setup properly to me and current shooting style/habits/whatever, it was easy to get into a comfortable and no/low tension shooting position.
2) Higher magnification helped, at least in this case. My previous scope was 4-16 and my current scope is 7-35. While the quality and price ranges of the scopes are vastly different, I still think the 4-16 is OK for the ranges we were shooting at. However, the added mag available helped a lot. First was better able to spot my misses. I typically was shooting at 25x and I could see the near misses WAY better than with my 16x. I didn't shoot at anything more than 30x for even the longest distances. Mirage is not an issue at this location. The added magnification also helped in combination with the grid style reticle and making quick adjustments, particularly on the wind calls. The added magnification allowed more defined measurement of the miss and allowed for quicker adjustment.
3) Quick follow up shots in the challenging wind conditions at this location is key. That was something I picked up from a couple of friends with experience shooting longer ranges as well as videos. In the past, we would shoot, confirm with the spotters and and then make adjustments. The confirm with spotters for me often was because I couldn't pick up the near misses through my optic. With both upgraded optic and better spotting scope, we were able to quickly confirm the near miss and make a quick adjustment, with less time for the wind to change. The best string I had was a near miss and then two successive hits at the 1000ish yard target.
4) Rangefinder with the ability to measure the incline/decline is key. One shooting buddy has one, but was not able to make it to this session last minute. The folks who usually shoot at this location had ranged the targets previously, but didn't have info on if they measured "close enough" and if it accounted for the angle. They typically walk shots in if they miss, so accurate ranging is less of a premium to them. We are striving for first shot hits.
5) I need to practice reading winds and making adjustments. This is particularly for shooting with headwinds or tailwinds. I "think" I have gotten better at wind calls laterally, as I've been spending more time on that recently. But I found that at this particular location, the head/tail winds were leading to many of the near misses. At least I think. I was hoping to true the data on my ballistic app, but wasn't able to for a few reasons. Even then, I ended up being 0.8 mils off the elevation at 1000ish (we were thinking the true range was in the 1050-1080 yard range). The ammo I was shooting was some hand loads that I had good velocity data on and at least decent grouping (not based on completed load development), but was confident it would be "workable". I was surprised at the difference since the ballistic app had previously proven to be pretty spot on in the 200-700 yard range. However, the true range may end up being the key. Of course as well as my shooting capabilities.
Overall, a very fun session with the bolt gun. Some good results for the bolt gun as well as my handloading. Looking forward to seeing if I can be more consistent as I refine the load development for this rifle.

Shot some long(er) range last week. This was the same location that I shot with my bolt gun prior to the upgrades/updates, go good before/after comparisons.

I'm deciding between a few finalists, with Defiance and Curtis the top two.
Then when you were chambering your barrel, any specific considerations? For me. I want to maintain the range of being able to shoot from the magazine (so 2.800" to 2.810"), but also not "jumping a country mile" when I shoot the 168 gr hybrids. I think I will stay in the 168 to 175 gr range, maybe into the 180s or so, but don't envision going to the 200+ range, at least not yet. I'll be keeping my current Rem 700, which I am able to shoot the longer cartridges.
So many choices. . .

Going to be ordering a custom action for my bolt gun soon. For those who have gone the custom action route, any specific considerations for your choices?
I'm deciding between a few finalists, with Defiance and Curtis the top two.
Then when you were chambering your barrel, any specific considerations? For me. I want to maintain the range of being able to shoot from the magazine (so 2.800" to 2.810"), but also not "jumping a country mile" when I shoot the 168 gr hybrids. I think I will stay in the 168 to 175 gr range, maybe into the 180s or so, but don't envision going to the 200+ range, at least not yet. I'll be keeping my current Rem 700, which I am able to shoot the longer cartridges.
So many choices. . .
A good gunsmith, that will chamber your rifle, should have an appropriate reamer for the bullet weights you want. Discuss with the smith at the time of the build. Heavier bullets in .308win is difficult, not enough case capacity to drive them. Anything over 175 is diminishing returns IMHO. Unless you plan on pushing the pressure envelope. ;) Also, 200 grn + is so long, forget about mag feed. You'll need to take up too much case capacity to fit into a magazine.

I was hoping it was that easy as going to my gunsmith and be like "I want this chambered to shoot X, Y, Z". I know some who have reamed for a specific bullet and smaller window, but I do want to shoot a range of bullets.
Yeah, I hear ya on the diminishing returns. Even with the 175 gr Bergers I sort of feel that. I'm testing the 168 gr Berger hybrids next. I am looking forward to those.
No, not planning on pushing the envelope. I think I am in an "ok range" with the 168-175 gr for distances out to 1000 yards. That said, I still want to try the 180-205ish to see how they shoot, but not necessarily out to 1000 yards. An yeah, forget about mag feed on anything longer than about 2.850ish with the "generous" lip on the feed ramp/lip of my Rem 700. ::) :(
That said, I expect to have to load one-by-one with these 168 gr Bergers. I'll have the 175 gr OTM for mag feeding, or at least that's the plan/hope.

We didn't have much time to shoot since it was near the end of the day. I got what I thought was a decent shooting position, which was different than the last time I had good success. The winds were very challenging with it swirling at the target (by the flags) as well as switching at the shooting position. The target is also in a spot where it's near impossible to see the near missed. I was all tantaran since the last time I had good success. I loaded up 3 rounds, dialed my elev and went at it. Misses. Switched to a "target" in the dirt near the target to try to spot where my misses where. That's what I did the last time I had good success. Where I spotted the near miss, gauged on the reticle and put two rounds on the target. The winds were more steady "into" that day, where it was switching all over in the recent session. I wasn't able to gauge the wind in the next 10 rounds or so. So as the day was winding down and sun getting low, tried the target at around 530 yards to see where I was at. The target at 530 is way easier as the winds aren't as bad at that target. Was able to put some rounds on that target, which I guess sort of confirmed that I wasn't totally off that day. That target is pretty easy with the .308 though. It a little more challenging with the AR and 1-10 scope, but didn't bring that gun that day.
Anyways, something to work on for next time I will hit the reloading room.

The new 169 SMK suppose to have better BC than 175 gr according to the forums.
That would be an interesting test.
Post by: macsak on August 31, 2021, 02:21:14 PM
Was able to shoot some longer distance a little over a week ago. Steel targets in the 500 to a touch over 1000 yard range. I was super busy in the weeks prior, so I wasn't able to load more of the more recent test loads that showed promise from the Lapua and Berger combo. I did have a bunch of Federal brass and SMK combo with a couple of powders from a prior batch that I rolled for longer range. So I had good chrono data and has success at the 1000+ yard target previously with the Varget load.

No, I haven't. With my 1:10 barrel, I've only shot 168 gr and above. I was intending to try up to the 220 gr range, but I've only gone up to 185 gr. The Berger 168 gr hybrids have a high BC for that weight range. I just started testing with that bullet when I got busy. I will likely stick with the heavier Bergers for a while. Because I have them and recommendation from my gun builder.
A buddy has shot the 150-160 gr range, but his barrel twist is much slower than mine.
Interesting test, eh? You should try. Go test um, Go test um, go. . . 8) :D

Now that the barrel is in, I’m in the chambering process. Estimated timeline is end-Nov/early-Dec window. Scope also came in, so just need mount and ready to go. Want to add a bipod just for the new 308, but can be ok with the one I already have. I may try a different chassis for the 6.5 CM. Looking at KRG for that one. the KRG chassis and components seem to be well stocked, so not the 3-4 month wait like the MPA.
Post by: drck1000 on December 10, 2021, 11:26:23 AM
I am doing some research on load development for both .308 and 6.5 CM. A couple of buddies, as well as gun builder shared their load data. Seems WAY more advanced than what I had done, so have some homework to do. ;D
Post by: macsak on December 10, 2021, 11:36:09 AM
Checked in with my rifle builder and the barrels have been chambered and guns now in "final stages". ETA was "before Christmas", but now looks like "around Christmas". Which is fine, though I was getting the itch back on centerfire B/A since I was gearing up for mid-Dec. I still have the scope mount to order, but that's about it.

Post by: drck1000 on December 29, 2021, 08:49:48 AM
Some initial impressions:
1) The MTU and M24/M40 barrel profiles are heftier than I envisioned. I had shot some rifles with those barrel profiles before, but I guess I never really stood out to me as much back then.
2) The bolts on these custom actions are suuuuper smooth. The action is melonited to a dark finish, which I like. How firearms and components function are most important to me, but still appreciate aesthetics. I went pretty plain/basic, but thinking back, I had a lot of options to "personalize". Base cerakote options included solid, two tone, fades, shades, texturing, and splatter.
3) The gun is a Defiance Ruckus, but exclusive to the gun builder, so it has specific markings. Including serial numbers too. Nice touches on that.
4) Overall balance of these two builds are way different. I went with a MPA ESR chassis on the .308. While I was waiting for the gun build, I ended up getting a KRG X-Ray chassis for the 6.5 CM build. Mostly to try the KRG chassis, as well as a decent "budget" stock for the barreled action. Balance point of the gun is not a super big deal to me, but something I noticed. The MPA is quite a bit heavier than the KRG. With the heavier profile and longer barrel length, that makes the difference more noticeable.
5) I have a Teslong bore scope and ran it through the new guns, mostly to test the borescope. But was interesting to see what a new custom gun and premium barrel looks like. At least before I get shooting.
Post by: Ocean19 on December 29, 2021, 07:26:26 PM
Been reading that other smiths are bedding actions in chassis's as well, supposedly it makes a difference in accuracy.
What barrel length did you end yup with on both calibers?
Post by: drck1000 on December 31, 2021, 02:25:14 PM
The conditions at the range was windy and rainy at times, but overall not bad. I don’t mind shooting in that type of conditions and would’ve gone even if the weather was rainy. Luckily I left before the heavier rains started.
Overall, I love the new rifle. I had already noticed the attention to detail from the gun builder, but function and performance is the key. Through the first 40 rounds out of the new gun, I am VERY impressed and very excited to get into hand load development.
Highlights:
1) Velocity with the 26” M24 barrel is about 200 fps more with FGMM than the 20” SPS Remington barrel, at least early shots out of the new barrel. Supposed to get about 50-100 fps speed up. Noticed about 20-30 fps increase in average velocity in the first 40 rounds.
2) The heavier M24 barrel, MPA ESR chassis, and Area 419 Hellfire match brake made a noticeable difference from the Rem 20” SPS barreled action with MPA Comp chassis. Not that the recoil from the previous gun was a lot, but it’s a lot more mild with the new setup. Shooting for “more precision” is my interest, and wouldn’t think of shooting this rifle for hunting.
3) Very impressed with the performance right off the bat with FGMM. Posting some highlights in a follow up post, but I shot (5) 5 shot groups and the max was 0.45ish MOA.
4) The longer 26” barrel introduces some interesting support gear needs. First is a much longer rifle bag. I picked up a 55” bag from Scheels, which fits the new rifle OAL of approximately 50” well. However the shoulder strap has the gun carried with optic down, so need to be more careful. Second is longer cleaning rod. I upgraded to new BoreTech cleaning rods for the .308 and 6.5 CM anyways.

Second (5) shot group of the day with FGMM 168 gr.
The two other (5) shot groups were 0.466 and 0.423 MOA.
Overall, I think I could do better with FGMM, but plan is for next range session to be with handloads. Probably Varget and 8208 and starting with jam-0.020.

Loaded up some with Varget and 8208. Same load range from the Rem 700. About 100-150 for faster with this barrel (26” as opposed to 20”). Mostly shooting for data and comparison, as well as monitoring velocity for barrel speeding up. Seems like the velocity speed up leveled off. Total of 100 rounds.

did you adjust scope or POA between powders or groups?No. Zero’ed for FGMM, at least for now. Once I choose and dial in powder/primer combo, will refine zero. That said, I typically shoot with scope set for 2-3 mil low or will print out the offset POA/POI target.

Looking goodThanks!
Looking forward to getting into the load development for both the new 308 and 6.5 CM. Actually somewhat expected a bit better from this group of initial test loads, even when I knew they were part of the barrel break-in/wear-in. That was since I had seen good results out of the FGMM. The tests weren't that bad though, with results measured out to the 0.40 MOA to just under 0.80 MOA, with definitely many in there that were shooter error.

FYI, I've heard "from a friend" that 168 SHBTMK with 39.4g RamShot TAC gave slightly tighter groups from Rem 700 24" 5R than 41.5g IMR 4064 even though velocity was almost exactly the same (2570fps) .Thanks. I have plenty to try from. Sucks that I only have 1lb each of stuff like the RamShot TAC, VV (two different ones, can't remember the numbers), and another. Something to try.

When I get loading, I want to have a decent amount on hand. Varget, 8208, and RL15 top on my list. I have some 4064 as well, but think I only have maybe 1.5 lbs left. I had some pretty good results on my old gun with 4064 though, which is why I used up quite a bit. I think I also have a few pounds of H4895 as well. I'm sure I'll find something decent with the top three on my list. I'll try others along the way, but want to get to at least one solid load worked up before experimenting more.
Somewhere in there I'll start on the 6.5 CM. Have only H4350

Besides the first target, the groups were in the 0.523 - 0.772 range. I was actually expecting better based on the results I had with the FGMM, but these were random tests primiarily for watching barrel speeds.

Luckily a fellow shooter and 2a member was on the bench next to me and noted seeing splash in the dirt well ahead of the target, probably about 3 feet low. Spend the next 5-6 rounds shooting into the berm and noted adjusted the POI close to being back on paper, but noticed the scope was dialied well high. Decided to call it quits for the day.
Did some troubleshooting with the gun builder. Suspected scope issue, either scope itself or mount. So this week, I moved the scope to a different gun and the scope was fine.
Something else weird on the gun was that with the Hellfire brake, the collar wouldn't budge. Used a strap wrench and an adjustable plier/wench with leather to grip and collar didn't budge. Consulted Area 419 and they recommended tapping the brake with a rubber mallet. I did that and the brake body ended up being able to be moved/twisted, but the collar still wouldn't budge.
Looking at the brake, there were a few tiny spots of exposed metal (silver) through the nitride on the top of the brake. So suspect the brake alignment and slight baffle strike causing the low bullet impacts. I would take off the brake and reinstall, but the collar is stuck. Don't come loose or tighten down.
The barreled action will be going back to the builder later this week. Am sure the gun builder will make things right, just very strange.
I suspect the brake worked loose in shipping and alignment got off during shipping. Before shooting, I was able to loosen the collar and hand tightened down, but I didn't fully remove and put the brake body back on before shooting. I am guessing the baffle strike was enough to somehow tweak/move the collar.
Sucks a bit because I finally have all the 6.5 components in and am ready to do. But still have plenty to occupy my time with the .308 as well as the CZ 457.
On a positive note, testing the scope on the .308 was good practice and got some darn good grouping. Very excited about what I can get out of the .308 build.

Bottom line is that they builder tested the rifle and it shot well after replacing the brake collar. So I am pretty confident of the baffle strike theory.
Send the gun back Friday afternoon via UPS. They received the gun this morning. They worked on the gun, did troubleshoot, and gun is on the way back my way. So full turn around in probably less than a week.
Post by: drck1000 on April 09, 2022, 09:47:23 PM
Quickly got the gun zero’ed and shot a mix of factory match ammo and handloads. It was pretty windy at times, but didn’t mind. After zeroing, mostly watching the velocity as the barrel speeds up. Will likely shoot another 50 to fire fork and continue barrel velocity monitoring.
Overall, fun shot well.
This batch of 140 gr ELD-Match and H4350. I didn’t think the groups overall were that impressive upon first glance, but range was a little over 0.3 MOA to around 0.80 MOA. I was struggling a bit on some strings with my rear bag. Overall very happy with both the 6.5 and 0.308. Will shoot about 50 more 6.5 to practice and fire form brass. Then start the load work up.

Good to hear the rifle is up and running;D
Thanks! Good to know that it really was (parts of) the gun, and not me. ;D

RL15 with Berger 175 gr OTM. First time shooting RL15. Velocity was slower compared to the “manual loads”, particularly with the velocities I am seeing with Varget. Not good or bad, just observation.
0.31 - 0.62 MOA
Post by: drck1000 on May 08, 2022, 04:29:35 PM
0.26 - 0.85 MOA
Without the first group, rest were less than 0.5 MOA. Don’t recall anything off on the first group, but settled down nicely after that.

What kind of FPS you getting with both loads?RL15 41.0-43.0
2420-2570 fps
Well below book velocities. Likely will do ladder test higher.
Varget 41.0-43.0
2510-2660 fps
Slightly higher than book velocities with the 26” barrel. No pressure signs.

RL15 41.0-43.0Ahhh for varget 41 grains I’m getting about 2580-2600 FPS using 168 out of a 24” clean barrel. I’m just fire forming the brass so more testing to come.

Ahhh for varget 41 grains I’m getting about 2580-2600 FPS using 168 out of a 24” clean barrel. I’m just fire forming the brass so more testing to come.The velocities above are 175 gr and 26" barrel, so seems about right. Somewhat clean barrel as I shot the Varget after (3) shots to verify zero since I took the scope off to test the 6.5. Then (25) rounds of RL.
The RTZ and cold bore shots with FGMM were pretty much spot on. Maybe 0.1 mils left but that could have very well been the zero since most of my groups for the rest of the day were a touch left. Winds were kicking at times, so didn't bother adjusting.
Same with my .308. This was the last batch to fireform. Have (100) 1x fired brass, annealing and sizing next. Plan is to get into a pattern of brass prep for .308 while loading and shooting with 6.5 cm, and vice versa. Then throwing in some days to shoot/test .22 lr.

How was Saturday’s test?It was ok. Mostly was for fireforming brass to get to 100 1x fired cases and general practice. I had shot/tested the same setup (powder range, primer, brass, etc) 2x previously and noticed that the velocity Sat was around 20 (as high as 30) fps. I thought the velocity had flattened out, but assume the velocities were due to temps. It was pretty hot over the weekend.
I now have fireformed brass for both 6.5 and .308, so will start on the load development next. Powder test, then seating depth test. Just trying to decide which component combination to run with.
How did your testing go?
Post by: Ocean19 on June 08, 2022, 01:07:36 AM
I found 2 powder nodes to test around 2600 or 2650 fps. I went as high as 2763 with 168 gr bullets.
Next will be seating depth test. I have an idea where it should be just need to test the powder loads at that seating depth.
Post by: drck1000 on June 08, 2022, 08:01:28 AM
I had velocity changes since the my first test just keeps going up. 42 gr varget getting around 2650 FPS. Finally getting around to testing the custom die for a tight chamber, now that i got 100 pieces of 1x fired brass I’m on the load testing again.For the velocity changes, you think that's barrel speed up? Or other factors?

You're about the same state that I am with both my .308 and 6.5 in ready for starting load development/refinement. I'm likely going to start with 6.5, but plan is to have both in the works, but staggered.

For the velocity changes, you think that's barrel speed up? Or other factors?My 308 was speeding up till about 200 rounds but seems like its leveling off. As the barrel gets dirty I gain more FPS. I shot 25 rounds one week to fire form following weekend same load gains about 10-20 FPS down a dirty barrel. Never fails

Noticed maybe 10-20 fps delta higher in the latest batch of test/fire form loads for the 6.5. I haven't been tracking temps, but I do know that the recent range sessions were way warmer than the initial range sessions over a month ago.

Finally picked it up from the FFL over the weekend. Haven't been able to shoot it yet, but seems quite solid and incorporates some tweaks from the "traditional" Rem 700 actions. Main one is the incorporation of a trigger hanger. It makes swapping out a trigger VERY fast. I read the intent was to facilitate quicker trigger maintenance in the field, where many times triggers can get gummed up and fail during competition (or field use). You can swap out a trigger with very simple tools, assuming you have the tools to take the action off of the chassis/stock. I can see how that could be a very useful feature for many, but for me, it's a nice to have. Swapping Rem 700 triggers with the pins are a slight PITA, but not hard. I am not one to swap out triggers regularly, so not that big of a deal. I can't really see changing out triggers during a match with the traditional pins.
One thing about the trigger hangers is that there are many chassis that will require some modification. KRG is one chassis that required milling of a section of the chassis to accommodate the trigger hanger. I was able to install the Impact into my KRG and function check was fine. While it appeared to fit, I decided to put the new barreled action into an MPA chassis that I had after I got rid of my old Rem 700 barreled action.
I hope to have a scope mounted on the Impact setup later this week and maybe head to the range.

Nice what caliber is the new barreled action? 6BR? 6BRA? 6 BRX?All of the above. Multiple barrels. . .
Nah, I got another 6.5 CM, but slightly different setup. Doing some side-by-side testing with the "older" 6.5. ;D

There you go bro! That's honestly the best thing going these days. Being able to change out barrels n use one action for multiple cartridges is the best. Less to deal with registration wise etc and you can have barrels shipped straight to your door boom done. We were doing it for years with our blaser's but they don't make it in whatever cartridge you want per se. But it was great and super fast to change out the barrels in the blaser no need to screw it into the action etc. Congrats on the new barreled action :shaka:

Right now, I reload at a buddy's shop and have to put away everything after each session. That's fine, but takes up a bit more time to setup things and get going. For now, I'm concentrating on .308 and 6.5 and have specific setups for each gun. So with the Forster co-ax press, it's pretty quick once the dies are setup. If I had more space, I would setup stuff like a vice and other stuff for things like you mention and working on guns in general.
Once I get to a "good point" with .308 and 6.5, I may venture out further. I've been looking at 6.5 PRC and a couple of different 6 mm variants.

Details:
Impact Precision 737R
Benchmark M24 1:8 twist, 4 groove, 26", 0.185" FB
EC Tuner Brake
MPA BA Comp Chassis
TT Diamond 2-stage
Athlon Cronus BTR Gen2 4.5-29x56 APRS6 Reticle FFP
ARC M-Brace Rings
This started as a barreled action that I got a really good deal on the action. I also wanted to test the tuner brake, particularly for factory ammo, as well as have a back-up rifle for my "older" 6.5. Barrel lead times are 9-12 months in Bartleins, so this will also help when come time to re-barrel this gun. The intent is to shoot these a lot, key work being intent.
Shot some factory Hornady 140 gr ELD-M (my baseline for 6.5 cm) and some Berger 144gr LR Hybrid Target. I typically am not one to do a formal barrel break in. For my ARs, break-in is shooting them, a lot. For my firt two custom bolt guns, I followed the builder's recommendation on shooting 100, then clean. That's about what I would typically have done anyways. For this one, the gun build recommended shoot 20, then clean, then shoot 20-40. So not that different, so I decided to follow his advice. Since I was planning on shooting 40 rounds total, I took some basic cleaning gear to the range with me.
Highlights:
1. The Cronus scope on this rifle is intended for my .22 lr rifle. I'm on a waitlist for another scope, so decided to pick up this scope as an opportunity to test/try the Athlon line, as well as something to get the 6.5 up and shooting. I had started off with the Ares initially, but ended up returning it for the Cronus. I am very much one to want to try things side-by-side. While I haven't shot the Cronus side-by-side next to my NF ATACR and ZCO, I can definitely say that the Athlon Ares and Cronus are excellent for the money. I've heard excellent things about the Midas line as well. However, while I think the Cronus is an excellent optic, it's not "just as good as" the other scopes. The clarity of the Cronus is excellent, and even the glass on the Ares was excellent. However, there are definite differences in the glass and even more so in the finer details of the scopes. Things like tactile clicks don't really bother me, but it is noticeably different. Simple things like how to adjust the zero stop, or even to remove the scope caps are seemingly better thought out on my other scopes. Could very much be that I am now used to them, but simple things like the cap to adjust the scope caps are prone to moving the turret just by removing them. Or details like how the diopter on the Cronus is able to move freely, whereas the others are able to lock down once adjusted. I haven't done the tall target test yet, but that's next. The glass is quite clear, I can tell differences between the NF and ZCO. Will it make a difference in the type of shooting I will do? Probably significant, but I did notice a difference.
2. The gun did NOT like the Berger factory ammo. I did some measuring of the jam before I headed to the range. The FB on this rifle is shorter than my other 6.5 cm. It's about 0.02 jump from the factory ammo. Most indications are that the 140 gr ELD-M like 0.05-0.07 jump (for reference, but I'll go with whatever ends up having best results). The Berger 144 gr LF Hybrids were about 0.100 jump, which sounds about right for the hybrids.
3. Cleaning at the range, especially when windy, is a PITA. I mean it's fine, but you don't have everything and comfort of your home. First time I've done any cleaning at the range. Didn't help that my cleaning rod is I think 56", so a PITA itself to get it to the range. I did notice that after the first 20 shots, the carbon coming out was pretty thick. I don't recall how my first 6.5 cm looked after the first 100 rounds. Barrels are barrels, but something I did notice.
I already have brass and some Hornady 140 gr ELD-M to test. I was also able to get some Berger 140 gr hybrids with the help of a super cool buddy, so have those to test as well shortly. Just have to decide which gun to test them with.
