I know many are going to say, "just buy buckshot", supposidly cheaper and easier. But buckshot are not pure lead. Somewhat harder and lighter weight. I cast .315 round balls all the time, (in fact need to cast some this weekend), with a lyman single mold. It is no problem to cast perfect balls in .32. Just get the mold up to temperature as with any other size ball. Doesn't take much lead either since the ball is so small. Hope this helps, Jim.
