I am new here. I have found what might appear to be a cannon ball. It is between 5.1" and 5.2" in diameter depending where it is measured. It was rusted and pitted from being in the ground. I cleaned it up a little. It weighs 19.2 lbs. It has a large #2 cast in the ball. I live in civil war country. Sherman's army passed through here on his march to the sea.
