If one is getting gas cutting on a bolt face with a plunger type ejector they'd be well advised to closely check that ejector and spring..........Had an experience with an '06 BAR that was a loose primer pocket victim......that gas cut the ejector to inoperability and cost me a really good deer.
Better still, get RID of those loose pocket cases when you first discover 'em!
