Your best groups consistently from a gas gun

[simonp]

So, I am going down the rabbit hole of chasing precision from a gas gun, simultaneously working on developing both my shooting skills and precision reloading skills. It's a fun journey for the most part, I would be lying if I said there was never any frustration or bumps in the road!

I know a lot can be done when loading long in a gas gun if one is willing to single feed but I became curious about what realistically are the capabilities shooting either a 55/77 Berger or 69/77 SMK that is magazine length? I would be curious to hear your results, see targets and load data (I debated whether to post this thread here or in the reloading forum if Mods feel it should be moved please do so). I would like to see results at 1-300 yards ideally and although if you have a target and load that you shot in the ones when all the stars aligned that's great but really want to know data that is consistent, on any given day if you do your part it will perform at x level.


TIA

41.5 4064 + 175 gr SMK.

Not 223, but used for hunting and general asshatery. Holds about MOA in DPMS large.

The rifles I make are all guaranteed to shoot sub 1/2 MOA. Achieving Sub Half MOA with a properly built Gasser and handloads isn't all that difficult.


6.5 Creedmoor.

.308

.223

I really dont shoot the Mouse guns any more, I had a bunch of 6x5 .223 pics on my old phone but they didn't make the transfer.

I've been using the 69SMK with 24.5gr RE15 or Varget with the 69 set to 2.28" for over 20 years. I don't use CHF or chromelined barrels but SS or Nitride with a Wylde chamber should do 1/2" easy.
I've used Kriegers DCM (20")short chambered barrels that you have to finish the chamber and crown for a long time. I have shot .151" and .176 groups at 100 with those barrels, yes best groups ever. I'm not that good, especially after coffee.

ETA GI mags should allow 2.28, pmags will not.

Factory mk262's
Criterion core 12.5
MV in the 2630 range
Nightforce atacr 1-8

Range finder read 103y from muzzle

Pretty consistent around .8moa with factory ammo. I'll take it.

Whose hand guard is that? Just curious.

@SolidCopper Q. They did a clear ano honey badger run last year or so

Im a novice compared to a lot of these guys with gas guns. But they are easy to get shooting right with good parts. Both guns are shooting 77gr SMK’s with TAC powder and no brass work other than FL sized and trimmed to length.
