I think you guys are definitely right. After looking at the pictures in the link, I'd say its a shotgun slug also. It measures about 1.5mm in diameter and looks exactly like the one in the other photos. I'm embarrassed to say, but I'm not sure what it is made of(total newby here). It was found in Pendleton County, West Virginia by my great grandfather. He passed away in 1965 so he would have found it sometime before then. I have a whole box of arrowheads, fossils, and other things that he collected around that area. There are some indian mounds there and if anyone is interested in the French and Indian War there is some history with that in Pendleton County as well. (See Fort Sybert massacre). Thanks for the tips and replies!
