Thinking of getting into 300 Blackout. However, not sure. Can invest in reloading the 300 BLK but is it really worth it. I'm in Ohio now and see the price at cheap $20 and most match at $45 per 20 rd. All sold out also. Why not just stick with 308 if it's about the same price?

same mags and lower as an AR
lots of range in weight of "projectile", so you can load subsonic all the way to max velocity
less powder usage
i had the chance to shoot some subsonic rounds, and we were all laughing after every shot
-
if you plan on just shooting supers a carbine gas length will work. if you want to playing with subs and supers it would be easier with a pistol gas length plus 1 in 7 or 8 twist.
easy to reload for and easy to form brass from 223.

I'm a BIG FAN of the 300 BLK cartridge. My favorite loads consist of either Sierra 125gr MK or the Speer Hot Cor 130gr flat point or JHP.The Speer bullets are the most accurate out of my rifle. I prefer using H110 powder. Including the cost of the brass which I purchased for $0.10 each, I am reloading this round for $0.49/round. Much cheaper than you can buy new ammo for. It is well worth reloading for this round. Winchester 296 is pretty much the same thing as H110. Also, IMR4227 works well with this round. I have yet to try Lil Gun. I load only supersonic rounds because they are cheaper.
I brought a few old hard drives to the range one day to destroy so I didn't have to worry about my data being mined from them. I hung them in my frame per the rules. My .223/5.56 AR poked .22 caliber holes in them. But the 300 BLK blew large half inch and larger holes in them. I'm thinking this round in JHP would be a good pig gun up to 150 or 200 yards.
-
brass formed from 223 brass
subs................$0.32 per round (666 rounds @10.2 grs 4227)
super..............$0.41 per round (378 rounds @18.5 grs H110)

Any more people getting into 300 BLK? I'm starting to think about trying but bullets (for reload) still expensive. I may be wrong but 16" barrel seems like the only option for 125 gr. ammo. Would swapping the barrel from a mid 1990's era Bushmaster A3 upper work?
That way if 300 BLK dies out, I'm not out big bucks. Complete 300 BLK uppers selling for over $1000.

I am sure if you look hard you can find a complete 300 BLK upper selling for over $1000 but if you look harder you can find them starting around $400 and up. My first Google search netted one on sale at Midway for $399. And you can find one for less without the BCG and charging handle. You can use the BCG and handle from your 223/5.56. They are exactly the same. If you want to change out the barrel, you can do that, too. I am sure for even less.
What is the basis for your statement "I may be wrong but 16" barrel seems like the only option for 125 gr. ammo." ?

Looking at 300 BLK barrels online are either pistol lengths or 16" and for HI 16" is the only option. Looking to shoot 125 gr. weight ammo. Also what is the recommended feed ramp design and gas length for 16" barrels?
I see some with carbine and some with pistol length gas systems. Checked Midway and they do have better priced complete uppers.
My thinking is to take my time and buy the barrel parts then later rails, BCG, charging handle.

Sorry WhyNow? I do not know enough about building my own upper to be able to answer your questions. I purchased a complete upper for my project. I bought a CMMG 16" carbine length upper. Paid around $450 for it. I shoot only lighter (supersonic) 125gr-135gr heads.
Barrel length of 16" is probably limited by the design of the cartridge.

Depends what you want to use it for.
If you are looking for a subsonic suppressed round, it's pretty nice. No sound, no flash, low recoil, light weight for the bullet weight.
If you're shooting long distance IMHO don't get it.

I think everyone is putting M4 feed ramps on their barrel extensions now. I don't know if it matters.
Go with carbine length gas with a carbine buffer. Pistol length is ridiculously short. I have a Wilson combat barrel with carbine gas and it works fine with lighter 125 grain bullets but short strokes with subsonic. If you have "short stroke" problems you can always drill out your gas port or fool with different buffers. I've read that subsonics work better with a suppresser.
I hope that answers some of your questions. 300blktalk.com is a great source of information.

We do sub sonics and use a 240gr HEAD. BUAHAHA
Ah you blackout band wagon boys..sub sonic 240gr might as well just shoot 45acp. 300blk is all hype don't know why anyone would want one :-*

There's a lot more to ballistics than bullet weight and speed.

Thanks Inspector, powdermonkey, GZ and Justin for your input and info. The 300AAC BLK FAQ is very informative. That seems like the go to forum on 300.
Plan to wait for the November sales for a good barrel, flash hider and gas parts unless I see a deal on a complete upper that can't refuse. Meanwhile get some cases at the show and order some dies and look for powder.

For the light bullets, you can't beat Hogdon 110 or Winchester 296 (they are the same powder)

Want to get the carbine gas length barrel for the lighter bullets. Your 2nd link lists Midwest Gun Works which sells a AAC 16" barrel (BAR09105C) for a good price but sold out right now. As soon as it's in stock I'll jump on that.
-

Hope I can find these powders. Normally I check JHara, WGS, YG or SEC since they sell Hodgdon and WIN powders.
-
wouldn't wait on the midwest deal........don't think they will get any more. it's been months since they last had it in stock.
-
1680 is a good powder as well. I like 4227 in my loads. It a do it all powder for 300blk. Not the fastest or lowest charge type of powder but it meter well and runs cool.
-

I have tried most of the available powders in my 300 BLK (Except Lil Gun) for supersonic loads and my results are all pretty close. However, I found with my rifle and loads the H110/W296 works the best. Plus since this is magnum pistol powder I use it in .357 Magnum and 45 Colt/454 Casull loads.
-
powders I have used for 300blk
H110 / W 296 for top velocity for super with 110 to 125 gr (prefer to use for super)
A1680, W 680 and H/IMR 4227 both for super and subs
H/IMR 4198, W 680, H/IMR 4227, A 1680 for subs 190 to 240gr (prefer to use for sub)
-
I'm going to try WIN 296 since it's also used for .357 mag loads.
Just ordered Redding FL die set for 300 BLK. On my way to spending more kala again.

Just a suggestion for bullet selection. I had my best results with Sierra 125gr and 135gr Matchkings. Also I had excellent results with Sierra 125gr SPT and Speer 130gr HP and 130gr FP. Not saying other bullets won't do just as good or better. Just saying these are what worked best for me. Currently experimenting with a 135gr Lead Spire Point as a cheap plinking alternative.

Thanks for the info on bullets. Probably start with Sierra 125 gr HP matchking. Sierra site has good info on load data that can crosscheck with Hodgdon data.

For guys that load with H110/296 and 125 gr. bullets, what kind of primer do you use? Hodgdon/WIN load data says to use SR magnum primer. On some forums others use SR or CCI #41 primers.
This is for 16" barrel with carbine length gas system. Also anybody try 110 gr. bullets (like A-Max) with H110/296 from a 16" barrel?
-

I use Federal 205's and CCI 400 and 41's. I use mostly the Federals since those are the oldest and what I have most of. I have not had any ignition issues with any of these primers.

I like CCI #41 and will probably use this.

cci work well. if your using h110 and 125gr bullets then you will most likely find a good accurate load with 17.3 to 17.7gn of powder but as always work your way up.

Being at work and not being able to look at my load data. I believe my most accurate load is at 17.5gr. :thumbsup:
-
Will start with the minimum that Hodgdon lists 16.7 for 296 then go up from there. Probably end up close to your guys loads.
Hope to find some 125 or 110 gr. bullets, primers and some 300 BLK brass at the gun show.

Has anyone here tried using AK bullets as an alternative? I just loaded a batch of 50 at varying charges. I'm still trying to work with the seating depth since the bullets seem to have a different ogive. I'm loading to 2.045" COL.

Be careful when choosing a bullet to use in your 300 BLK. You are supposed to use .308 diameter bullets. Some AK bullets can be .312 or larger.
-
I mic'ed the AK bullets that I have at .310". When seated, the case neck outer diameter was .3325"-.3330". They also seemed to drop in nicely into a case gauge. How can I check if the bullets are chambering too far into the leade?

You can try making a dummy roundwith a bullet that sticks out way too long. Measure the length and record it. Then shove it in the chamber and snap the bolt shut on it and make sure it is closed completely. Pull it out and re-measure. If it got shorter then it should be just touching the lands. I would back it off 0.01 and call it good. But don't forget you are also limited by the magazine. You make them too long they won't fit in the mag. Max length to fit in the mag is the same as 5.56/.223 which from memory is 2.26. All of this depends on the bullet design as well.

My load for sierra 125gr matchkings is 18.1gr of W296 and cci400. They run right at 2200FpS out of my 18 inch barrel.
I no luck with 110gr hornady vmax and 110gr m1 carbine bullets. even the factory hornady 110's sucked out of my gun. barnes 130's worked well but expensive.

Where'd you get the Sierra 125 gr. MK's from? That's what I want to start with since Sierra has a nice load chart on their site.
Why did the 110 gr. Vmax suck, poor accuracy or velocity or both?

There are probably only two places on the island I know of that sell Sierra MK's. You can try YG's and WGS. You will pay dearly for them. Online sites you can find them at decent prices include Powder Valley and Brownells/Sinclair International. I know Powder Valley ships USPS Flat Rate. Don't remember about Brownells/Sinclair. If you have a Cabela's credit card I think they still have their $5 shipping for a $99 order. When I order from Powder Valley I usually split the order with some friends to cut down on shipping costs even further. Just a suggestion. If you order from Powder Valley, also check out the Speer 130gr bullets. Cheaper than SMK's and shoot comparable in my rifle.
-
I get all my bullets online. Local gunshops only seem to cater to hunters.
As for the 110s, accuracy was just terrible. Like 4-5 inch groups at 100. Maybe they work for your gun.
My barrel is a Wilson combat 18" 1 in 8 twist carbine gas.

My barrel is 16" 1 in 7 twist also carbine gas, so might be different. May buy a 100 ct. box to see or try the Sierra 110 gr. Varminter bullet. The Barnes 110 gr. is too much $ right now.

Inspector, I ordered bullets from Powder valley before and they were pretty fast, only thing their online ordering can be a little difficult. I also see Brownells has them for $180 + free edge shipping.
P.M. , have you ordered from OK Weber before, how were they in shipping time and overall satisfaction? They have the lowest price I've seen and ship USPS.
If you guys have 16-18" barrels and carbine gas, what kind of buffer and spring do you use for supersonic loads?

Justin, mahalo for the buffer info. What's your opinion of ordering from OK Weber?

I would order from OKWeber. They are a reputable shop that have been around for years. I think they are a small operation. Sometimes small shops take a few days to ship.
