Who was it who used their blackpowder revolver to defend his home from unannounced visitors? I want to say Jason Ballou, only problem was the visitors were a drug task force used a search warrent at the wrong address.
result Jason shot in the head after his wife , who was nude when door was kicked in, screamed and he picked up a muzzle loading revolver and stepped out into his living room.
Sorry if I went into old history. Black powder works just fine, just beware of cops with search warrents.
