I have a PSA and a Rock River .308 rifle, and I'm trying to build a 3rd PSA rifle, at the moment. The RRA will not shoot anything but brass ammo, I tried shooting some cheap ass silver bear ammo, and the spent case would get stuck in the chamber, but it shoots brass just fine. The PAS will shoot the cheep stuff, but at this point I've sworn off anything in .308 that is not brass. The RRA is a 1 MOA rifle, the PSA is prob. close to a 1.5 MOA rifle. Right now I have a hard on for the .308 AR's. The 5.56 has gotten to be the same old thing to me.
