Is there an issue Match grade 7.92x57 load?

M75 was initially issued when M76 was introduced, which was a "match grade" for it's days.. Those days it is supplemented by commercial PPU match ammo, which is basically M75 with non-corrosive boxer primer.

My M69 with M75 gave about 1.25-1.5 MOA for 5 rounds groups with slow fire (1 shot every 15 seconds), with faster firing groups opened up a bit to about 2-2.5 MOA. . From my experience that is about the result you can expect from M76 also, with caveat that M76 heats up faster. Better shooter could possibly do better, I know that a friend did sub MOA group once, using M69 with M75 ammo.

It is '60s tech, what do you expect? :) Practically all period sniper rifles also experience same thing, opening of the groups as they heat up.

Now for something weird, from Maksim Popenker's blog. "Revolving hunting carbine" in 9x39 and 12.7x55 subsonic rounds, based on RSh-12/RSh-9 revolver. Being based on that revolver it has no cylinder gap gas leak problem and can use silencers.

Oh, just realized that those are even weirder than I have thought. Like RSh-9/12 revolver, barrel, cylinder and upper frame recoil on firing, and cock a hammer. Cylinder is not rotated however, and is rotated by pulling a trigger...

Yeah, that was given as a reason for RSh-9/12, use with shields. A lot of SFs use revolvers when working with shields, due the "maximum reliability" as there is no way to clear stoppages.

Wondering zero when heating up s encountered with... drumroll... MG42, so we can say it is a German tradition. :D

Watch where the tracer goes and change the QC barrel earlier?

The issue with the M69. If you do rapid fire with a bolt gun you are probably in a target rich environment and not in a good way. ~ 2. 5 MOA accuracy is the least of your problems.

Not issue of how much barrel is hot, but how much receiver heated up. It was most noticeable in very cold weather. OTOH, it is a machinegun.

You cannot have this in USia. Yet.

They can not have Russian made ammo anymore, because... "human rights".

If PPU...

PPU has full schedule for next 4 or 5 years, despite expansion.

I was just saying but a good point. Anyone who can sell to the US, probably already is as much as he can because Americans buy ammo like crazy for over a year. They might be able to get more components from Russia but if their entire manufacturing line is running at full capacity already. They'd need the machinery from Russia and floorspace and personnel. 

This would be a good time for a revolution in North Korea.
