def was, homie.

I am sorry to resurrect this thread, but I figured it was better than a new one given the information already gathered here

I finally put together and shot my 6.5cm AR10
Pertinent details:
18" criterion barrel with RLGS, Rubber City Armory high pressure bolt, and a 6.5CM specific heavy buffer
Result: flat primers and ejector swipe and a noticeably stronger recoil and report than the Hornady factory ammo I also shot.

I am of mixed mind whether or not to try it in my bolt action.

Who load were you shooting? and bullet weight? I've seen the same signs with a near spec-out rifle as yours that a friend shoots, using factory Hornady 123gr SST

I cannot see any difference in fired cases and unfired cases. Can anyone point it out to me?
These were fired in my Sauer 100 6.5 CM.

Those look good to me. Even nice radius edge on the primers. Throw a caliper on the case head above the rim on a few of the fired and unfired. See the difference. But they look good to me.

I have shot about 2 and a half boxes of Whitetail with no hint of "overpressure". Also can't understand why bolt actions would be be considered less safe for shooting an overpressure cartridge than an AR 10?
