An acquaintance of mine has a 1889 Marlin that he brought tome with the action jammed and a separated case in the chamber. I was able to remove the headless cartridge case, but the chamber is badly bulged, I suspect from shooting too hot a smokeless round. I am not up to fixing it, and would appreciate advice on doing so.
I own a Winchester 1892 in 44 WCF and enjoy shooting both black powder and smokeless. It is surprisingly accurate with Clays smokeless powder and hand cast bullets.
