I anneal for most bolt actions but not yet for my AR's, Mini 14/30, and M1a's. The automatics tend to have forward bullet creep from the abrupt motions in chambering. Given the same interference in bullet to neck fit of .003", the un-annealed cases have more grip on the bullet than the annealed ones, lessening forward creep when chambering.
The bullet creep is more of a problem in the larger 308 and 6.5cm where annealed cases have up to .010" creep. The non-annealed cases have 0-.005" creep. I brush and sonic clean all brass and seat bullets without any lube for the autos.
So, I'm wondering how others deal with bullet creep in auto loading rifles.
