Well, you can put powder, a gas check, shot, and an inverted gas check into the case, crimping lightly over the inverted gas check. You might PM Wilbe Lead for his load info, as I've seen him make some very accurate, and useful loads this way. He cleanly shot the head off of one critter with this type of load. The gas checks do a fair amount of damage to small critters at close range, not to mention the shot column.
