Looks copper dug it about four inches at a old minors town. It's strange I think.

It is a copper-jacketed bullet, meaning, a lead bullet with a thin copper jacket covering all or most of the lead. The one you found dates from the early 20th-Century through the present. Here are photos of several varieties and calibers.
