Very cool! DNA testing would most certainly be interesting, if that was still possible. It might have missed its mark, or been a through and through. Who knows?
Chaffee sent me this bullet some time back that's from Adobe Walls. If he sees this I'll let him explain how he got it since I forgot what he told me. The 45-70 and 45-90 brass is unrelated to it. Gun is a .45-70 Shiloh #3 half octagon tapered.
Click away, Chaffee. I'd like to see them.If I have the gumption, I'll take a photo of all the ones I have...if anyone cares to see.
