It does look similar. It's definitely not 7.92 Kurz; not 7.62 x 39 Russian. Might be a .308 Winchester case shortened and formed to fire a ~.324" bullet but it's not anything I recognize. Can't be a longer cartridge (like .308 Win) or it would push too far into the chamber. Might be 8 x 57 Mauser case, shortened. Might even fit in a military bolt action rifle chamber in some way that I'm not aware of.

I'm waiting for my end mills [mail] so I'll look in COTW and see if anything looks similar...

Got this at a gun show back in the 70's or 80's.
