Caliber identification

[zybysco]

Any thoughts? It is being compared to a 22lr. The rim really throws me off. I compared the rim to a 32 auto. It looked minutely smaller.

Do you have calipers to measure the bullet diameter?

What does the headstamp say? Edited November 7, 2015 by nightrunner

That's definitely a first.

[zybysco]

No headstamp at all. I should have listed that. No markings. A customer brought it in and said he has a bunch of them. He left me one to try to identify. My intention was to bring it home and measure it, but I left it at work.

[zybysco]

It is a centerfire.

[runco]

Wildcat for sure, but maybe a 32 rimfire necked down to 22 or 25 my guess.  I am googling now.

Except for the bullet profile, I say this may be it (a 32 necked down to 25), its called a .25NAA (.25 North America Arms):

That thing looks a lot older than from 2002.

[nightrunner]

Looks like a .30-32 cal bullet. And that's a significant bottleneck with a sharp shoulder. Not to mention being a rimmed bottleneck cartridge that short, rare indeed.

This is something very old. That's a true rimmed case not the semi rimmed .32acp style.

How about this?  297/250 Morris Short, 4th from left to right:

The rimmed case really confuses me.

297/250 Morris Short  is my guess

[zybysco]

297/230 Morris Short I'm thinking now. You guys are pretty good.

So how did you acquire one assuming you have one?

[gregintenn]

Cool. Does said customer also have a Rook Rifle chambered for this cartridge?

[zybysco]

I doubt he does, but he apparently has a ton of the ammo. Looks like it is worth a decent amount. I suppose he could have a rifle to shoot it stashed away somewhere. He us supposed to call me next week.
