Took the newest addition, a CETME .308 Sporter out to Left Hand Canyon to test fire a couple mags. 40 rounds NATO Port surplus Brass case FMJ 0 failures 40 rounds Silver Bear Steel case FMJ 0 Failures 40 rounds RUAQ Steel case FMJ 0 Failures 20 rounds Federal 150 Grain soft point. 4 empty cases failed to eject. Didn't stovepipe, When I cleared the action, they were sitting lengthwise on the next round, which had stripped correctly out of the mag. I guess I can't really complain since the cheap a$$ ammo performed perfectly while the $17 a box stuff, which I'll clearly have no reason to buy again, but it seems odd. Since I've read that the NATO round is a lighter load, the performance is counter-intuitive. I'm no genius when it comes to ammunition but why would what is ostensibly a .308 sporting rifle cycle the NATO type stuff flawlessly and not the "sporting" class ammunition. It held to just over an inch so I'm happy with the accuracy. Must have got a decent one in that respect. It's not like I'm going to head out looking for Mulies with it so not reliably cycling hunting ammunition isn't all that important. Anyhow, overall, I'm pleased with the new purchase, but thought I'd see if anyone had a similar experience or knowledge regarding this.
