Chas, due to the ridiculous nature of our Keystone state wild life officials, we cannot use certain guns for hunting. Our options are simply center fire, rim fire and muzzleloading. A cap and ball revolver does not load from the muzzle, but from the front of the chamber. The EMF offerring is indeed a revolving muzzle loader in every sense of the definition muzzle loader.
While in your state, they may actually have wild life officials who are informed about firearms, we are not so lucky. That EMF muzzle loader, would solve a problem. If there was a way to put a front sight on it, even better.
