Bullet Casing ID

[Dan-o]

Found several of these casings at Fort Boise park.
It looks like a rim fire cartridge as it doesn't have a primer.
Any ideas?

Thanks for looking.

looks to be in the 45-70 family.

I'd say it is probably a .50 U.S. Carbine, which was introduced in 1870. It was one of the first metallic cartridges, and were usually used in cap and ball guns that had been converted.

That is not an inside primed cartridge , it is a cartridge with the primer missing . Inside primed have no hole just like a rimfire cartridge.
No way to tell the cal. without a measurement.
Measure the diameter and length.

Ok ,so that is a firing pin mark in the picture I thought it was a hole with dirt in it.

the one i have is cleaner and shows a firing pin dent, not a hole ,the way it looks it was a large firing pin with a strong spring.
