You find the strangest things! I've found canister shot before but not that big. The ones I've found where iron but I think they used lead as well. Maybe Cannon ball guy can Enlighten us.
You could have something good there.
It’s weird because it was deep and if it was lead I’d think it would have patina. I did find it at another part of this park maybe it was mixed in with fill. Didn’t find anything else worth talking about. Strange
