Like said, keeping the chamber clean is job 1. After that, an extractor from Kidd or Volquartsen fixes problems a big percentage of the time. When I ordered my last Kidd extractor, I also ordered the recoil spring kit. A factory rate, a light & a heavy. I like em.
One thing I caught on the last I worked on was that the extractor groove in the bolt had rolled over edges from the buffing process that impeded the full travel of the extractor, not even the Kidd part helped this gun. The groove or slot had to be opened up.
A reliable gun now, with almost any ammo.
