My uncle used to have a leather bound box in a drawer in his library with a pair of nineteenth century flint lock, black powder dueling pistols. When I was a kid, I used to sit in the leather chair next to the desk and play with them.
These days I suppose the police would confiscate them if they knew they were there.
Indeed, when I got older, I made some black powder (carbon, potassium sulfate, and carbon powder, and fired a few shots at a tin can.
Sorry, meant to say carbon powder, potassium chlorate, and sulfur.
Potassium nitrate, not sulfate.
Rick Harrison the co-owner of the World Famous Gold & Silver Pawn Shop, as featured on the History series Pawn Stars, could buy these, because if you don't know, Rick does NOT HAVE A FEDERAL FIREARMS LICENSE.
How, might you ask can Rick buy such weapons (I believe pre-1900's) or as long as the pistol cannot take a metallic cartridge. They are exempt from much of all the federal & most state law(s) because they are considered antique's.
P.S. If your a convicted felon, you could own one of those Black-Powder only pistols / rifles.
