Well, unless things have changed, you can own a cannon, if it is an antique cannon. It was so heavy, that he had to move it by truck and trailer. The somewhat narrow steel rimmed wheels would make a mess of an asphalt street.

Had a friend who had a naval cannon on his front lawn. He had a steel rimmed wooden carriage built for it. Every 4th of July he would shoot it (with no projectile).

When I lived in Florida, I was friends with a guy who was a Civil War re-enactor. He had beautiful cannon. The annual "Battle of Olustee" was really loud.

I owned a couple of cannons during my career as a Civil War re-enactor. Black powder weapons are not considered “firearms” under Federal law so there is no restriction on those.

As I understand the law, it is still legal to own a fully automatic modern firearm or a modern artillery piece, but everything must be registered with the Federal government and there is a high tax on them.
