Odd piece of brass

[Mattroth54]

I found another piece of brass I don’t know anything about. It’s a 9mm case, necked down to 32 caliber bullet. The headstamp is 22 32. What is it? It’s the center piece in my pic. Left is 357 sig, right is 9mm.

Also an interesting round, but mine is for a 32 caliber bullet.

If I was to guess, 8mm Nambu.

I think you're on the right track. Older Asian or European cartridge. 30 mauser maybe? 7.62 tokarve?

Never heard of that one. After looking it up I’d say very good guess. The Nambu is shorter than 9mm case. This one is longer.

9mm is 19mm long.
8mm Nambu is 22mm long.
It also could be either a 7.65mm Borchardt or 7.63×25mm Mauser.

What is the length of the case?
Plus it's been fired, so the neck will be larger now.

looks like I crossed some wires. I’ll measure and take another look when I get home tonight.

proportions are wrong for the 8mm nambu.

looks like a 7.62 tok, 7.63 mauser, or 7.65 borchardt from the pics.

Most likely Tok. If the length and shoulder measurements are right. Old hard brass when fired tends not to spring back much like new brass will.

After measuring and checking 7.62 tok specs, no doubt this is what I have. Mystery solved, to the scrap bin. Thanks!
