I've got two of the old Dixie Gun Works bag molds they had made for them in Italy. One is a .495, the other a .440. both throw slightly out of round balls that shoot, as far as I can tell, as well as any commercially swaged ball.
I also have a Callahan mold, and the only, and I mean the ONLY downside I can see is no sprue cutter. So I just use the sprue cutter on one of my Dixie molds. I don't bother trimming the rest of the sprue off, I just load 'em. I suppose if a man had nothing to do he could spend a few minutes trimming sprue remnants, but it gives me hand cramps.
When I get into a high output frame of mind, I fire up my Lee lead melter with the pouring spout and cast with my Lee two cavity molds. An hour of that and I'm good for many, many months.
