Impact marks on breech face

[Pbaker29]

It a build using Ballistic Advantage barrel, bolt is Sharps reliabolt, carrier is a RCA low mass, ammo is/was hand-loaded (23g H335 w/55gr boolit, CCI 400). The round that was stuck never fired, and I had difficulties extracting it. I cycled it several times trying to get the extractor to hang on. Once I got the round out, the primer was damaged, telling me that it was at least striking the primer. I still do not know why the round was stuck, but subsequent firings showed no additional issues. Even with a stuck round though, it does not explain why the bolt is now impacting the breech face. In previous cleanings, I have not noticed this damage. My only assumption is the bolt was contacting the breech face on the 4 or 5 attempts i made cycling the BCG in efforts to extract the stuck round.

I guess my second question should be, is this ok to leave as is or do I need to fix/replace parts?
