[QUOTE="Pdvdh, post: 1389246, member: 4191"] Appreciate your thoughts Steve. I don't think I've overlooked anything that points to operator error, or another (better) explanation. But it's generally good to receive and consider others' thoughts. A secondary interesting observation in the process of examining the bolt head: This is a BAT Machine Company HR action. The action body and bolt were salt bath nitride treated by BAT Machine company. I've seen bolt faces following blown primers on other bolt heads that were not nitrided in the past and normally there's a slight, yet noticable erosion pattern on the face of the bolt face - in a circular pattern matching the diameter of the primer pocket. The escaped gas torches and etches the bolt face. The nitride treatment coating seems to have helped protect this bolt face from that erosion. Look's smooth to me. I'll have to scratch the surface with a needle and feel for an eroded surface. I do see the ring where the gas hit the bolt face, but I do not see any erosion into the bolt face. [/QUOTE]
