Yes, I had to do considerable research on the Mauser and the differences between .308 & the 7.62 NATO and the wasn't a lot of information to be found. Like I mentioned, I ran one round of .308 through it and could barely open the bolt because the the case expansion from the higher pressures. My Remington .308 will eat either round safely. Live and learn, and if I live long enough, I'll be a genius at some point.MeMelYup wrote:Be careful shooting 308 in a 7.62x51.

The wall thickness of the NATO ammo was well suited for this particular rifle whereas the commercial ammo.....not so much. I have reloaded the 7.62 and the only problems I have encountered is with the cheaper Aguila brand ammo. For some reason the primers tend to seat a tad lower in the primer hole and I've had a few misfires. So I don't use them any more. I have reloaded .308 spent brass at the recommended specs for 7.62 NATO and have had zero problems...........so far. The .308 die and set up works just fine. Hope that helps.
