Help Needed: ID of cartridge/shotshell

I need help ID’ing this cartridge or shotshell. Actually I think it has something to do with a mortar initiation charge, but I am unsure. My thanks in advance.


Any guesses?

Chris, is that a projectile at the front? If so, probably not for a mortar. Sub-cal for an RPG or other AT launcher???

Don’t know what the round is, but based on the word “metak” I would start with Yugoslavian (Serbian?) ammunition.

This is a Yugoslav 20mm subcaliber cartridge for the M57 bazooka.
The projectile has a tracer. There exists also one with a nose fuze and charge inside.

Here the projectile as shown above:

Here is a picture of the box.


AWESOME! Thanks everyone!
