The weather turned cold so I’m inside sorting through old junk boxes that for years I’ve thrown unknowns and other items that really didn’t fit into my area of interest. Sorry, here’s another one. It has a copper washed steel case and a struck primer. It has a domed green plastic wad.
Rim: 10.70 mm
Base: 9.54 mm
Case Lgt: 16.45 mm
Total Lgt:17.73 mm
Any thoughts would be appreciated.
