Rimfire shells. Year?

[ResurrectedVirginia]

Just curious what company and what time frames these casings were made. If I remember right the diamond shell is 32 cal and the US is about 30 maybe a little under. Thanks.

Those look .41 Short. The diamond is Western. That is what the .41 Derringer used. But if you already know the case diameters - the manufacturers would be the same.




"US" is the United States Cartridge Co. of Lowell, MA.
