It was a gorgeous day at the range and produced a lot of great data. After so many days of rain, it felt like a summer day from my youth. The air always seems cleaner after a good rain. At some point, they’re gonna have to dump a bunch of aggregate rock in front of the silhouette parking to cover up the mud.
It was very busy at the range. I ended up at table 25 which is way too short for me but I made do. The chrono was giving me errors and misreadings from the rifles next to me. I wonder if this happens more at the far left end than say, table 39. Caldwell told me they’ll send me a replacement screen, hopefully soon.
6.5 Creedmoor: After resizing the cases, I noticed some "wrinkles" in the Peterson necks. I didn't feel anything with the scratch test, and I annealed the cases again. Afterwards, I had two of the old Hornady cases with cracked necks and took them out. Peterson now only sells their cases through Grafs which charges extra for shipping to Hawaii. I might try gowesttrading.com but they only sell in packs of 200.
Started with seating depth testing with the Hornady HP Match 140gr and Superformance 41.0gr. The 2.80” worked really well with a nice 0.607 moa group. I didn’t have the chrono set up until the last group so don’t have complete velocities to compare.

I next shot two sets (5x10) of 29.5 to 31.5 gr IMR 8208 XBR and 140gr Nosler RDF. The 30.0gr grouped best for both sets with low velocity SD. Next time will try 29.7 to 30.5 gr.

I bought the RCBS hand primer so for grins and giggles, I primed the spare Hornady cases I had and created test rounds of 39.5 to 41.5 gr H4350 and 140gr Hornady Match. I bought more H4350, IMR4350, and Varget at Roy’s Fishing for $31 each. I also bought IMR4064 at $28 for the Mosin. These are crazy mainland prices!
The break was called and didn’t want to wait until the next break to bring the target in to 50 yards, so I shot the rest at the metal target and recorded the velocities. The rounds seemed accurate, but the chrono was starting to freak out. Being selective with the data, the velocity SD were low with an amazing 0.6fps with the last group. The 40.5 gr went all ding-batty so not sure what was happening.
1911-22: I bought high velocity Aguila and Armscor ammo at the Gun Show from Kaleo. I was hoping the higher velocity would work the action better and not jam so much, but this was not to be. Both were slower than the
standard high velocity Blazer ammo. I felt like the Armscor was more accurate than the Aguila. More testing to follow…
MN 91/30: I was having fun with pistol loads and jacketed bullets. I used the Hornady 150gr SP bullets because they’re the most accurate in the rifle and only cost 26cents each at Cabela’s. I started with 13.0 to 15.0 gr Unique. This powder is not positional dependent, so I didn’t include a filler. The 15.0gr shot a great 1.476 moa group with a low velocity SD. Next will try 14.7 to 15.5 gr.

Next was 13.0 to 15.0 gr 700x. I added a Dacron filler which again cause a comical scene of fluff shooting out of the barrel. I received several questions from passersby. After the first two groups, I thought the set was going to be a bust, then the 14.0gr had an excellent 1.508 moa group. The velocity SD were not as good as Unique. Next will try 13.7 to 14.5 gr.

AR-15v2: I used my homemade AR with the pulldown sights to try some of the Bushido .223 ammo I picked up at the Gun Show. The OAL averaged 2.213” with an ES of 0.018”. Devin said he seated to the top of the Hornady cannelure. However, I can’t see the cannelure on any of the rounds. The cases were trimmed but did not appear to be deburred. The brass are from 7 different manufacturers with Winchester primers. The average velocity was 2769fps. The SD was probably not a fair measurement in this rifle so will have to try with the varmint AR after I get the scope back from Vortex. I have to say that the rounds made a satisfying chunk sound compared to the PMC factory ammo. I was playing with the sights but overall, it seemed accurate.
