@Cubreac: I have a Rapine 577-470 trashcan mold that I acquired in a trade of sorts. I’ve never used it because I also prefer to shoot historically correct Minié or Burton balls. (Are trashcan style bullets historically correct? I never thought so but I truly don’t know for sure.) if you are interested in trying out this Rapine trashcan I could probably cast some for you. Now I’m curious to try them myself. However, I think you can get persistent, accurate results with a more traditional Minié ball, at least for casual plinking. As others have suggested, if you want to be a competitive shooter go talk to folks at the N-SSA. Maybe a trashcan will be the way to go after all.
