The retort from a cannon can be had with just a roll of tinfoil with an amount of Black Powder inside. In my small cannon ( 1.625 bore ) I use 300 grains of black and in my full size "field piece" civil war replica (pop can bore) I use 1/4 lb of black...not really much difference in the retort...both will wake the dead, but the muzzle blast/fireball from the big gun is outstanding. n projectile needed for full retort/blast effect but if I do use a projectile then the recoil becomes a factor. With a 3 lb projectile at BP velocities ( crono'ed at 1175 fps) that big gun ( aprox. 600 lbs) will recoil back 4 feet in the wink of an eye.

As for the legalities now, they are in limbo at the moment. For years if they were fire with a fuse they were considered non-firearms in the firearms legislation but 2 yrs ago as Cuslog mentioned the powers that be introduced a regulation thru IOC that any "devise" that has a bore of 20 mm is now a prohibited devise. I was going to mention this at the time on this forum but was "censored" from gun politics conversation by a mod at the time so thought "what the hell if he doesnt want to know the ramifications to folks on this forum so be it.
Just got called away from the computer so will continue this later.

can you fire a shaped/jacketed projectile through a smooth bore barrel? or what was the reason to fire a lead ball? lead ball easiest to cast?

I have almost zero knowledge of tanks, artillery or ships weapons, but I believe at least some of those systems are firing a shaped projectile down a smooth bore, you referenced firing a pop can which is obviously not round (well not a ball it is round)

still asking for a friend

Don't know about cannons, but they make rifled slugs for smooth bore shotguns. The rifling is on the projectile instead of the barrel. They work pretty well under the circumstances. All my kids started deer hunting with rifled slugs.

I doubt round balls are very effective. Too easy to get a bad spin with resulting hooks. My 177 Pellet Gun out shoots my bb gun by a very wide margin.
