I have a marlin model 1894 .357/38 its the pre remilin with the jm barrel stamp. the problem is it cycles .357 rounds fine but the 38 jams while coming out of the feed tube. I have had this happen before so I took it apart and polished the carrier to nearly a mirror finish but still don't want to cycle the 38's. i have tried with live rounds and dummy rounds too. does anyone know a fix for this other than not use 38 rounds of which I have a abundance of or is there a fix? Thanks GD
