Marlin 1894 44 magnum

comboy4evr knows what he is talking about. It takes some work and experimentation, but Micro-Groove barrels can shoot cast bullets quite accurately. Some have said a hard bullet is better, but I've had good luck with wheelweight alloy. Usually a bullet sized as large as will chamber in a loaded cartridge without difficulty will be the right diameter.

My Rossi 92 has .432 rifling also. If you want to shoot commercial cast Dardas sells a 240gr .433 that feeds and shoots good in my rifle. Also NOE makes .432 molds that drop .433 for me all day.
