Well, there's a suggestion for someone who is armed with a shotgun and finds himself in a desperate need of slugs. Take a shotshell, and make three cuts on the shell between the powder and the shot,to make segments of a circle so that the top and bottom parts of the shell are held together only by minor segments of the shell (I wonder if I put it clear enough - almost cut the shell, but not the wad, in half). Now when the shell is fired, the head will break off and fly away with the shot enclosed into it. For all practical purposes, it's a slug. I've read reports on that, and once at a patterning board it happened to me accidentally. The "slug" made a perfectly circular hole in the board, rather below POA at 35 meters. There was no damage to the gun, but it was a heavy waterfowler with fixed Mod. choke.
