Re: Unknown Rimfire Cartridge
.41 Swiss (aka 10.3x38R Swiss Vetterli). Years ago, there were so many surplus Swiss Vetterli rifles imported here that American makers, including Union Metallic Cartridge Co. (UMC or "U") made the ammuntion. UMC later bought Remington and the company became Remington-UMC. No .41 Swiss ammunition was made in the U.S. after WWII, and I suspect that round was made in the 1920's.
