You should be able to look this up in Cartridges of the World. It is probably an old .44 or .45 caliber center-fire (that little dot in the base is a primer). If you have pair of calibers, send measurements and I can look it up for you.

No Calipers, I sure wish I did though. Would love to know what it is. Like I said, It came from the area of a known campsite from the Custer expedition to the Black Hills in 1874. Found a great book about this that has GPS info on campsites, topo map info and photos from the exact same locations where photos were taken during the expidition.

I'd like to point out that all of the photos show [b]less[/b] trees in the area in the 1800s than today. so much for the tree huggers arguments.
