View Full Version : Cartridge ID

September 25, 2006, 02:23 PM
I recently purchased this unusual looking cartridge, and am trying to ID it, it is rimmed and rimfire. The case appears to be made of copper, and is approx. 1.5 inches long, OAL is 2.2 inches, the bullet dia. is about .420, rim dia. approx. .625. And has a capital U stamped on the head, which I assume stands for Union Metallic? Doing some research it looks a lot like the Swiss 10.4X38, an old military round, but I'm not sure? I thought possibly some of the old single shots like the Ballard may have chambered for a round like this?

Sure looks like the .41 Swiss in the next room.

Does appear to be UMC.

I would agree, it's a .41 Swiss (a.k.a. 10.4x38mm).

I believe thats it, I wonder if UNION METALLIC made the cartridges for the Swiss or if there were other rifles chambered for the round?

Definitely a .41 Swiss.

If I remember correctly Francis Bannerman brought in a TON of these rifles and sold them as surplus sometime in the early 1900s. UMC made the ammo commercially for the US market. As far as I know, no US company has ever made ammunition for the Swiss -- they are entirely in-house with their ammo production and always have been.

No rifles in this caliber were ever produced commercially in the United States.

Remington MAY have chambered some rolling blocks on speculation, but I'm not 100% sure about that.
