Question about breech loading cannons

[BADGER BOB]

Have read posts about legalities of blackpowder cannons but not clear about a cannon that is breechloading-such as a 12 ga firing yaght or signal cannon.A standard 12 ga shell will fit the chamber though I would never use anything but black powder.Any comments??? :? Bob

the blank firing signal cannons are not designed to
fire a projectile. when you load fixed ammo with
a projectile in the cannon it becomes a DD.

edited to add don't get caught with 12 gauge shells
anywhere near a signal cannon. this could be proved
as intent.
