unknown cartridge
Happened across a cartridge the other day, supposedly a 25-20 WCF, which now has me wondering if it is a 25-20. For starters there is no sign of there ever being a headstamp. That's a first, for me at least. Then in comparing this casing to a factory casing I find that it's shorter by .20" with an OAL of 1.178", from the base of the rim to the bottom of the shoulder is roughly .790", OAL of the round is 1.496", round nose lead bullet. Diameter of the bullet is .258 at the case mouth. I'm doubting that this is a factory round due to the color and shape of the primer. The primer has the appearance of a Federal primer and it's flat vs. the slightly convex appearance of a factory round.
My photo attachment abilities are eluding me today, otherwise ...
Sometimes I can muddle my way through it!

The round on the right is a 'bona fide' 25-20 WCF, the round on the left is a question mark.

When I click on it, it shows. In other words, I don't know.
I'm not paid to think anymore.
I'll try it again, after that ...

Definitely two different cartridges. Shoulder on left is considerably lower than shoulder on the right.

Could it be one of those British rook rifle cartridges?

Maybe one of these? From "Cartridges of the World" unfortunately no dimensions. I guess with longer neck, maybe the ROOK cartridge.

Is the base diameter of the two cartridges the same? The rim thickness of the 25-20 looks a lot thicker than the Rook so maybe someone turned it to fit? This could explain the lack of a headstamp.
But this is just a guess........

This is my guess.

What's the base diameter? It's close to a Tokarev 7.62x25 but not exact.

I load for the 7.62x25, definitely not it.
The rim dia. is .397, base dia. is .347 and with the aid of a magnifying glass see that there is no extractor groove on the casing.
