Ah, a crimp around the ring. I'm going to run these through my case prep machine and see what happens. I have about 100 cases left. I ran out of primers and projectiles.The easy answer to this question is yes - more often than not the 5.56 range pickup I get has crimped primer pockets, and they aren't always staked. It's usually a ring crimp.
These days I have batches of brass - brass that I know I've processed, and brass that isn't processed and needs to be decapped, sized, primer pockets checked, and crimps cut out of the ones that need it.
