[QUOTE="Pdvdh, post: 2613562, member: 4191"] If that ring is rough and pitted, it means that a casing leaked gas around the primer and those high pressure gases cut into your bolt face. If there's no cutting, erosion, pitting into the face of the bolt, nothing to be concerned about. It's impossible to tell by looking at your photo. Take a Q-tip and some bore cleaning solvent and clean up that ring. If after cleaning, you can see pitting of the steel bolt face thru a magnifying glass, you had at least one primer leak combustion gas and it torched your bolt face, cutting into the steel. This is normally caused by an over-pressured cartridge. [/QUOTE]
