Help identify an old cartidge case

mikekuzara

I found a fired cartidge case while on a jobsite. This is along the Bozeman Trail in Wyoming. It is a bottle neck cartidge of around .40 or .45 caliber, rimfire, with a large U stamped in the middle of the head. It has 2 firing pin marks directly across from each other, so was either out of a gun with a double rimfire firing pin, or misfired and attempted again.

It is 1 1/2 inches long, the head is 5/8 inch across, the larger portion of the case, below the bottle neck, is 1/2 inch in diameter.

Any help would be appreciated.

What about the 44 Henry Flat ?? Confused

I dont know about rimfires much but I do remember hearing about this one. Smile

Hey Mike...Ya gotta picture??? The "U" sounds like Union Cartridge. A for runner of Remington. I think...

Hi

I was thinking about the Spencer rifle's bottleneck cartridge.

I couldn't remember enough about it, so I have to do some Internet surfing.

You can find some NICE PICTURES OF OLD CARTRIDGES HERE. Among them, in Pic #15, is the Spencer .56-46 rimfire.

See anything that looks familiar?

Keep us posted, Ok? I love this kind of stuff.

Yup, the "U" is the headstamp of Union Metallic Cartridge Company, which Remington bought and absorbed.

Hey Mike, you managed to get some pics of that cartridge case yet? I am intrigued as to what it may be.

Cheers, Vince
