Recently purchased a pre-safety 1894, in very good condition. It is my first lever gun, in fact it is the first rifle I have owned since the late 70s. I was really excited about taking out for the first time today. I wanted to avoid lead ammunition, and have a rebuilt shoulder likely to be sensitive to recoil, so I bought some Magtech FMC flat point 158 gr .38 special ammunition. This ammunition would not feed. It jammed, but at least not in a serious way--i could unjam it--but I spent most of my range time either trying to figure out why it was jamming (length of cartridge?--the bullet end of the cartridge was tilted slightly down instead of up towards the chamber) or loading one shot at a time. The good news it is quite accurate, the bad news, of course, is that it jams on this ammunition. Any suggestions as to what my next step might be?
