Somewhat new Uberti Comchaero in 45 Colt shot in 3 matches, the last a state blackpowder championship. Several times it would not extract a fired case, costing me time. After cleaning the rifle, yesterday in practice it FTExtract 2x, but these 2x a live round came up in the lifter, keeping the fired case from being extracted by hand. Had to tear the rifle apart at the range the 1st time. 2nd time I simply placed it back in the rifle case and took it home at the end of the day where I tore it apart again. While apart, cleaned it very well. Noticed the extractor had a bit of up/down, .035", movement. Not "springy" movement like i'd expect but free movement.
1st question. Is the extractor movement allowing it to slip over the case rim?
2nd ?. Should I maybe polish the chamber.
3nd? Anything I might do to the prevent this issue I'm not thinking of? Maybe the OAL of 1.542" is too short compared to the 1.575" I get when loading HSM or Laser Cast 200 RNFP?
Light, sub minimum Trail Boss load under a Lee 200 gr RNFP. Actual weight between 211-216 gr.
