So, I was around a site that goes back to the late 1700s. I doubt this is that old but it looks like lead. It seems solid but almost like a rock inside. I don't know. I found some bullets online that resemble it. It almost feels like a rock. I wasn't sure if it was maybe a sinker. The color is slightly bluish as well and not pure white like some of the other lead I have dug at the site.
