How perfect would a bullet have to be if it were encased in a plastic sabot/wad and shot from a shotgun? How close in size does a ML bullet need to be? I've used flush-cut side cutters on sprues and can get about as good a cut as I can with a regular sprue plate. It's the outer edges of the base that really are the key to bullet accuracy, the divot in the middle isn't all that important on a slug that big. If the diameter was right it might be a good mold for a few bullets, but I bet it would wear faster than a mold with a two piece design and detachable handle system.
