Topic: Unknown cartridge

[Stojan Kostic]

Hello,

I've got this unknown cartridge for ammo identification. I'd like to disassemble this cartridge but I have only one piece. Does anybody know, what kind of ammo it is?

Training round?

Perhaps some variation of a Russian SP-4 round or related round?  I've never seen one in person and don't know much about them, so this is pretty speculative.

It could just be a weird homemade assemblage of junk, for all I know.
