The ammo has to be Winchester .308 on the box. A 7.62x51 NATO doesn't fit flush into the chamber on the PSS model. I have some T/C Encore barrels that might be OK. I had to put my box of 7.62x51 NATO away until I have something with a proper chamber.

The converse problem with putting .308 into a 7.62x51 NATO chamber is too much headspace. It might not fire reliably with the case head not resting properly on the bolt face. Gas may well escape around the shoulder of the brass too.

I reload my own .308 with the 100 gr Speer "Plinker" for punching paper targets. Less recoil, good accuracy and total control of the cartridge dimensions.
