I asked over on the CMP web sight how to correctly install an extractor collar on a 1903 Springfield bolt and didn't get a lot of replies (not even from the one smith who seems to use that sight as a platform for selling his services). My one attempt at this was far from successful as it left me with an out of round collar. Any help is appreciated.
