If I were using that chamber, I would use the LMT enhanced 7.62x39 bolt made from AerMet alloy. Nobody has been able to break one with high volume 7.62x39 from 10" full auto SBR's, but they were able to break the extractor, which is one of the first failure points on 10" guns in any caliber if they are gassed hard with insane cyclic rate and early unlocking.
