My factory bolt head is junk, has been since day one. It's always has issues with off center firing pin strikes and ejecting/dropping extracted rounds in the mag well. The new PTG head instantly fixed both problems using the old parts (extractor/spring/detent ball, ejector/spring). I'd need a new bolt head, I'm not re-using the old one.
Question: other than appearance, what harm is there in the cratered primers shown with my PTG bolt head? I'm not chasing hot loads, and I'm using temp stable powder (IMR 8208 XBR). It could be an issue with high pressure loads, but not necessarily?
