You can still buy and bear a cannon with no background check or registration or any of the like, FWIW. Very easy to order on the internet and have shipped straight to your door[].

You can, but be aware that an exploding cannonball (widely available in 1776) is considered a destructive device, so each shell must have an NFA stamp. Solid shot is not considered a destructive device.

		Does the shell have to be serialized? Or does one merely need a stamp that handwaves towards a particular, but generic looking shell?
