I’m looking for someone who can identify what kind of cartridge case this is, as shown in the linked photo images. All I have is spent cartridges, so I don’t know what they looked like before they were fired. I acquired them in buckets of old brass from the estate of an avid marksman.
Side-by-side view of mystery cartridge, and a .308 dummy round.
It has the general appearance and dimensions of a .308 cartridge. But where the bullet should be, there is instead a long tube extension to the case.
The headstamp says “LC” and “85”. So this is a military cartridge of some type, from the Lake City Army ammunition plant.
Peering inside the neck tube, which is now empty.
Blanks are usually crimped on the end, unlike this specimen. I’ve never seen anything like this one.
Can anyone identify it?
