I had an original Conversion in 50-70. It was a nice gun. It predated the 50-70 being readily available so I ordered some Bell brass and cast up some bullets then loaded them above a case full of FFG. It shot nice. I missed a good buck on the last day of the season, near dark. Made a very satisfying boom and fireball. Personally, I'd rather have a conversion or replica thereof than to fool with the paper cartridge ones. I know people won't like this but...if you get a replica you could use smokeless and cut way down on the cleaning. If I wasn't concerned with exact historical accuracy, I'd get the 45-70 and you wouldn't even have to reload for it unless you were of a mind to. I'm sure Missouri Bullet Company has good bullets if you don't want to cast but do want to reload. You could drive right over and pick them up.
