I'm bored and daydreaming, so indulge me a bit. Who can tell me what it takes to get into black powder cannon ownership? And I mean an actual black powder cannon, not a golf ball thrower. What does it cost? Is there NFA paperwork, or is all of that negated because it's black powder? What kind of range/accuracy can be expected? What's maintenance like? Who makes cannons and carriages? What about ammo, can you order cannon balls in bulk? Are there clubs or competitions held? If so, what are they like? What cannons are the best? Are most of the ones available just replicas of Napoleonic or Civil War models, or are there modern designs in the same way that there are "modern" inline muzzle loaders?
