@BillRM,
Quote: Such cannons were around in the revolution war and they are now completely legal to own and are not even consider a firearm.
Bullshit, my neighbor owns 2 cannons and he had to fill out the forms with BATF, pay a tearly tax stamp (I tink the fireMarshall has that)
He also needs to have his ammo (powder) acquired in a registered manner and , if he would use "grape shot or anything explosive or withering, hed need to register the ammo and the charges (just as I have to for any explosives and caps I buy ON MY EXPLOSIVES (separate licenses for buying, transporting in a magazine, and USING)
Also, my neighbor MUST notify the FireMarshall about each time and shot he plans. (He shoots his cannons off every few 4th of July's)
Breech loading cannons are almot like buying a nuke, you become a "person of interest' in anything that happens in the county
