Cannonballguy is extremely knowledgeable. He will ask for exact diameter (use calipers) and weight (a scale that weighs in tenths of a gram). After that he can determine if it is a cannon ball or something else.
Yeah, I think I got that wrong. I think he only asks for pounds and ounces. Sorry about that.All I need is a weight... only in pounds... no need for "tenths of a gram".
And a good picture...
A location of recovery... or near...
And I will give you my "opinion" (heh) ...
OR I will narrow it down.
