I found this in close proximity (25') to a Eagle" C" button , 5 - 3 ring bullets and some other war related items. It is in a yard not far from a local skirmish. It is lead and 1.4" in diameter . Was hoping it was a cannon ball but I'm confused as to why the enlarged hole. The hole was not drilled, it was obviously filed out fairly crudely. It was in a dry location close to the house which explains why it didn't turn color, protected by the long soffit. Can any of you give me some idea of what I found.
