Alright so I inherited a bunch of .308 brass that had been being reloaded for an AR-10. I have bolt action. 308s and I found out if I didn't get my CL down to about 2.007 the rounds wouldn't chamber in my guns. The brass is starting out around 2.013 give or take so it's a lot to shave off of each case. I guess my question is why are my bolt actions so much more picky than the semi-automatic ARs in regards to case length?
