This looks interesting

I’m curious about the malleability of the case alloy for sure. Might have to double up arm day for the weak side of your press.

Blackhills OTM in the red box is not the 77gr the USG uses, It's regular not fast commercial ammo, about the same-ish as the PSA AAC 77gr. Accurate but meh. The USG uses MK262 which comes out of a 10.3" about 2424 and 2600+ in a 14.5" and 2780+ in a MK12 about the same as the Badlands 77gr brass equivalent. I looked at their site and their brass cased 77gr is pretty much exactly the same as MK262 with about the same price. Wanna try the Shellshock and see what it's doing.

Ammo not presented but is currently issued and in use, which would give a more realistic comparison:

MK262
M855 62gr
M855A1 62gr - this is the primary ammo

I figure somebody here will assume I don't like it and am talking shit about it.

Curiosity killed the cat.
I do wonder about metallurgy of alloy shellshock cases.

I have reloaded thousands of wolf 223 steel cases, it sized & deprimed same as brass 223/556 cases.

used same, press, dies (mandrel in sizer been spin polished), lube, powder, primers and p&p m193 & tracer bullets.

I only trimmed & champhered the necks on the initial reload, they didn't flow like brass and took very little trimming to uniform length, I also didn't crimp the necks on bullets, they held just fine with the sized neck tension.

Only draw back(s) is when I tumble the cases the first time after sizing/depriming to clean lube from cases it also removed the laquer coating so cases easily rusted if got damp/wet (it tumbled off easily though).

also the necks tended to split when firing on as little as 2nd reload, most I ever got was 4 reloads out of cases before the necks split.

Accuracy with the steel wolf cases with p&p m193s was bout the same as I got with the brass cased reloads.

anybody fired tracers whether they light or not know accuracy with them is hitting in general direction your pointing the rifle, sometimes they'll fool you and actually hit what you were aiming at.

I’ve heard really good things about the accuracy of the AAC 77gr stuff. It’s no barn burner but very consistent. I don’t suppose there’s anyone anywhere that has done more work in balancing variables in load development than the AMU. Simple logic dictates that some alloys and materials can handle higher pressures than others, but the total package of workability refuses to be ignored. More pressure obviously equals more FPS, but it also means greater bolt face thrust and lug shear stress. TANSTAAFL

I guess the emphasis that was omitted in the video is that case capacity is the biggest net gain. How efficiently it is used is up to the person stuffing it. At the end of the day how a person “FEELS” about it is immaterial. It’s kind of hilarious how that gets projected onto you. I’m all about a better mouse trap. A different one… meh.
