Wonder if this applies to artillery and barrel length, etc?

If it uses black powder and loads from the muzzle there are very few
restrictions. Anything over a .50 caliber in modern powders is under tighter
regulations. To sell a gun made in your own shop would require all kinds of
different permits from several agencies probably. The NRA/ILA website probably
has links to these laws and regulations.

Oddly enough, so does the ATF website.
