I haven’t been here in a while, but happened across an unknown cartridge today and figured that this was just about the only place where someone would be bound to know what it is.
At first glance I thought it was a .45-70 blank, but it is surely not. Here are some photos with it in relation to a couple .45-70 rounds- it’s the one in the middle. The headstamp indicates “1912 T.S. P.E.” and a “T” in a circle. From perusing measurements in Cartridges Of The World I’m thinking it’s not even for a firearm, maybe not even a cartridge?? The “primer” looks odd, like it’s just part of the case surrounded by a circle of plastic or something. The brass appears turned not extruded, and it’s definitely heavier than the M32 blank next to it.
It would be funny if it turned out that it’s just some odd tool and not even a cartridge. Thank you in advance for any info.
Rim thickness .054"
Case length 2.000"
