Dug in a field. This kind of mystified me because I’ve never dug anything like it. Rimfire, overall case length about 1.17 inches, kind of smushed but that’s the longest straight section. Diameter at base is .64 inches, and marked “U”, which I’m pretty sure is Union Metallic Cartridge company. I’m wondering if anyone can tell me what specific round this is. Any thoughts are appreciated!
