It’s about a 3” bore 12 pounder. It’s pretty short and lightweight as far as cannons go. So I could manipulate and aim on my own pretty easily.
You can load it with lead balls as shot. Something like 190 round balls that are .69 diameter roughly 1000 FPS. I can’t remember how much powder it takes. But it would be lots of powder and lots of lead. So I would need to win the lotto to feed it.
Somewhere there is a story of guy shooting a whitetail with one. I don’t think the deer took a step.
