Tough thing with hand loads will be fixing the brass. Mine tends to dent up the case neck pretty bad, though I've heard some tape on the receiver cover where it ejects can help but I need to replace the gas tube lock first (was broken when I got it). We'll see I guess, I've been happy with the 1.5 MOA groups I'm pulling out of it with good commercial steel ammo but can probably improve on that with hand loads and a better trigger (probably an ALG AKT). Notably when I had mine apart it looks like someone had already fixed the hold open at least once. Mine has a neutered bayonet lug up front which I guess is better than not having it all, but I don't see myself fixing it as cost to get one (probably $60-75), have it installed, and then deal with 922r and replacing parts for that is more trouble than it's worth. Would rather spend the money on a red dot or 8x42.

Also, the other fix for shooting heavier bullets I read up on is to install a screw in the gas block as a regulator. Don't see myself doing it though, though I've had a hard time finding .311" bullets in a 150gr FMJ BT.
