Off topic, but can you help ID?

About 40 years ago I found some bullets on a non-Civil War battlefield (1830s, between Indian Tribes out west in Colorado). I can't tell if they are from that era, or if they are later, or more modern. The area is remote, on private land, but there could have been shooters other than the combatants. Or, maybe . . . Can any of you date these to an era?

Also, I would appreciate any information on the shell casing. It was found a couple hundred miles away, on the Oregon Trail on a private ranch in Wyoming. It is way over .45 cal (my 45s fall inside it) and the priming compound appears to have been integral to the center of the case.

They look like .45-70 .458 in diameter, 405gr.

All post ACW. The brass casing looks like a .50-70 but I can't tell from my phone.

Thank you. Darn. Oh well. I think 50 cal. sounds right on the shell. I'm just starting to reload and I'm waiting for calipers in the mail. They will help size this stuff. The only cases I've ever seen without an installed primer were rim fires so I thought this was cool. More research ahead.

Got my calipers up and running. The shell casing is 1.781" long, .55" o.d. and .501" i.d. The slugs are .45" at least deformed spot.
