Is there a difference in ignition from a Win.Small Rifle - CCI Small Rifle - Remington 7 1/2 Small rifle primers. I have been using Win. but I can't get any latley but sort of hit the lottery yesterday, stopped at Bass Pro and they had a brick of Rems so bought them. Then I was lookin through a drawer of crap and found two boxes of CCI primers. Also I 've been shooting some PMC's 223, they were priced right and I thought I could reload a couple of times for 3gun. I started to prep the brass last nite and found a cartridge every so often that the flash hole was not centered. Should toss them or use them, I'm thinking toss'em.
