Though the minishells are delivering the power, if they can't be ejected, to serve up the next round, they are a no-go, unless the gun can be modified to deliver reliable function.
Refrigerators are not in season around here until the fall, after mating season with the washing machines is over and dryers get their lint on the antlers. Mini shells are just as good for hunting as regular sized shells at 5 feet distance away from the game.
