Found this today on Clark Island at Pymatuning Lake in NW Pennsylvania.
I assume its a musket ball? Its heavy lead, somewhat flattened on one side. Any way of dating these things? I guess muzzle loader hunting still happens here in PA so maybe its not too old?
Yes, hard to tell how old, but it does seem to have some patina. As stated, too small to be a musketball. No way to tell if it is rifle or pistol, both could be in the same calibers.
