I found this cartridge case while clearing my property in NE WA state. I would love to know what it is, but so far I have no clue. It holds a place of honor on my reloading bench.
It's 6.5" long, the inside diameter of the neck is 1.125", base diameter is 1.625", and the primer pocket is 0.3125". It looks like it might take a 209 primer.
No big surprise, I can't find this cartridge in Cartidges of the World ! The ruler didnt't photograph very well, but if you can zoom in enough, the scale closest to the case is in inches.
I wish I had a gun for it, maybe something like Krupp mountain gun. I love the idea of casting bullets for it !
