Well, I can't get my junky camera to focus in close enough to see the primer dent, have to take my word on that one.
I dunno, it looks like the pin rides flush with the face of the bolt, or that strange firing pin sleeve thing anyway.
I guess it wouldn't take much to move it just a micro bit forward and contact the primer.
So, check out your .223 guys - does your rifle put a mark on the primers???
Have any of you felt the need to get this taken care of?
