Has anyone on this forum loaded brass shotgun casings with large charges of black powder and say a .735 ball? In the old days, the 12 bore rifle fired heavy charges of black powder, and conical or round bullets on top. With this came recoil, but was quite effective on about everything up to lion sized game. If someone took say a mag-tech brass casing, just about as much fg back powder she'll hold and still allow room for an over powder card, a thin cushion wad followed by a lubed wad and just inserting the ball far enough in the case to lightly roll a crimp to hold it all in place? The ball would have to be a neat fit, but be able to pass freely through the choke of the shot gun. I have a Lefever nitro special shotgun, and with basic sights, would make a nice close range wild boar gun.
