I had 1/2 a day in the morning to myself today, so I decided to hit an area that I've been wanting to check out. No cellar holes found as I had hoped. As I was making my way down towards a small river, I was randomly swinging the coil on an existing trail (State land with some trails). I was getting a few strong signals here & there, but they were all very shallow 1-2". I pulled the usual shotgun shells and some modern pennies and a nickel. Then I had another strong signal, but this time it was deeper- 6". I dug it, and out came what I believe to be a 3 ring bullet of some kind. It has a very odd shape though. It does not have a cone shape at the point and there is no cavity, just a small indentation on the base. It is also not the typical whitish color- it is more grayish, but definitely has the weight of lead. Length is about 1" and diameter is 7/16". Can anyone give this a positive id?
