Hello fellow Wyomingite!! Its crazy how many cartridges Im pulling out the ground at this particular area. Many are rimfire, the majority of which don't have any writing whatsoever other than the "H" logo (these have 2 firing pin marks) The others that Im finding are center-fire, no primers, the majority of these cartridges have no visible writing except one. Clockwise "C 79 F 3". Other remarkable finds, there are many, is a Military Button, 1878 Indian Head penny (bad shape), and just today I found a large cast iron tea kettle. It was probably 3' in the ground and the metal detector went loco!
I can send ya some pics of the cartridge when I can a chance.
