I found a ammo cartridge in Wyoming and can not identify the headstamp. The headstamp is a "U" surrounded by a crest. The size of the cartridge is consistant with that of a .22 caliber ammunition. If anyone has any knowledge on this including the manufacturer, time frame, or where to look to find anything about this cartridge, it would be a huge help and greatly appreciated for my project.

Thank you,

The most common use of the "U" would be Union Metallic Cartridge, UMC. UMC was started in 1867. The parent company that owned UMC later aquired Remington. Remington and UMC were combined in 1912.

I have seen alot of .22 cartridges w/ a "U" but I cannot recall a "Crest". Pictures would help.
