I use the round ball paper cartridge in my 44 and it works really good. Very accurate. In my 36 I am using the conical. Harder to make the cartridge as I don't have a heeled bullet mold yet. Seem to just as accurate as it is with the round balls. The paper cartridges are a lot easier and more handy to load in the field. So much faster. Love both ways. Been loading powder and ball since 1968.
