You have to decide what it is you want to do. You either want to shoot cast lead, or you want a full-auto firearm. The only automatic weapon I can think of that may fire lead bullets is an original black powder Gattling gun. You really can't have it both ways.
BTW, the Thompson should only be fed jacketed ammo. They were designed to use fully metal jacketed (ball) ammunition.
Guns cause crime like spoons cause Rosie O'Donnell to be fat!
