    Best caliber for big game at 400 plus yards

    7mm to .338 magnum. Personally think .338 is not worth it with the .30 cal bullets available. 7mm is noticeably better for recoil. My "big" hunting rifle is a 7PRC.

    Pin and weld suppressor?

    I pinned a .338 Can on my .338 ARC barrel because I will never clean it and it will never wear out in my lifetime. Suppressors can go across state lines no problem, SBR's require 5320.a's.

    First shot dry barrel or oiled barrel effects.

    Oil isn't the worst idea for mid/long term storage, but before firing send a patch with alcohol then a dry patch. Tends to give about the best chance of not throwing the 1st shot somewhere weird, of all of the things I've tried.

    NITROCELLULOSE - FROM IMPORT TO END PRODUCT

    There's that new powder plant that was being built, and I haven't kept up with it, White River something? I think. Anyway I was truly surprised to see that start up because my opinion was (and still kind of is) that we've regulated ourselves out of that industry (and so many more). The water...

    NITROCELLULOSE - FROM IMPORT TO END PRODUCT

    I don't know much about the supply lines of the base material. I know there are some US manufacturers that nitrate cellulose, but no idea on what % that is. I believe I've heard that some comes from Canada, also. But as far as powder production, that is where the nitrocellulose is formed into...

    Does anyone stand with Berger?

    It's actually pretty cool in my book. Berger pretty consistently holds awesome weight variation and they make great bullets. I'm not arguing that at all. But I see this come up a few times a year where people dismiss a bullet because they weigh 0.4gr variation or whatever, and it's like dude...

    Infinition Doppler radar head over the last 6 years of being an engineer in the bullet plant at Hornady.

    Does anyone stand with Berger?

    While this is kinda fun, it's probably more true than most people will know... Typical match bullets (all brands included) show roughly 5-15% ES on net drag across the recorded Mach regime. Drag variability induced by the weight variation in this topic is on the order of 0.5% in the worst case...

    What's the difference between Black Hills 5.56x45mm NATO Ammo 77 Grain Open Tip Match and Black Hills MK262 MOD 1-C?

    For the .224 Aeromatch bullets we make cannelured and non-cannelured versions of 69 and 77gr. That is all. Published G1 BC's are always to be taken with a grain of salt. .355 vs .361 is within external factor variation (i.e. what barrel they're shot out of or what powder is used even).

    Ballistic Subject Matter Expert needed

    So the question is basically, "Why doesn't my bullet's exit vector match the centerline of the bore?" ? Some combination of, but not limited to, the following: - In-bore tilt of the projectile - eccentric mass of the projectile - non-uniform twist of the rifling - non- uniform cross section of...

    Hypothetical: 1x fired --> annealed

    I once shot a 20-shot group with a single piece of brass. Fired, annealed (AMP), FL resized, wiped off, trimmed, loaded and fired. This was in our 200yd test tunnel from the fixture. Group was pretty much indistinguishable from 20x virgin cases. The only notable difference was the first...

    Bump. Got no response from either person on the Magpul PRS stock. Potentially have an agreement on the XYLO extra pieces, will update as conversation develops.

    Geissele GFR Maritime Reconnaissance 6mm arc write up and review

    Had good luck with the 6.5 Outfitters (Rexus now I think) and Maxim bolts. JP we broke a couple of extractors but the lugs held up fine. I smashed and peened and broke several no-name budget bolts, which during the covid shortage was the reason for all of the follow-on testing because I got a...

    Geissele GFR Maritime Reconnaissance 6mm arc write up and review

    Bolts interchange in standard AR-15s. Not sure about reverse compatibility with other bolts but I also don't think you'd want to do that other than in a pinch. The G bolts have been among the best I've tested for durability/longevity.
