Has anyone made a paper-patch mould out of solid metal..what I mean is, chucking up round stock..metal of your choice..roughing out cavity with drills & finishing to size with a half-reamer. bullet would probably need a slight taper to allow removing. I know you could drill thru & use a small dia. ejector..with added benifit of hollow point if so desired..but I am wondering if a slightly tapered cavity, free from tool marks & using soft lead..which shrinks more, the bullet would fall out by itself or with light tap?
