I reload remington hulls. I was using rem primers but they were getting too expensive. So I switched to CCI I noticed they were not seating flush, but by a very very small amount. It seems like CCI has a bugle build. Winchester fit just fine though. My question is is it just the build of the CCI primers that cause them to seat a little off. And the other if a primer isn't totally set what is the danger to the shooter and the gun?
