What on earth is this stuff....

[Afy]

The entire cartridge is grey. .

Appreciate the help, and sorry for the crappy picture.


headstamp is aym 68. So likely to be corrosive.
Came in plain grey boxes, on stripper clips which were marked bxn 68.. quite curious.

Looks like 7.62x39 to me

7.92 kurz?

It is Czech 7.62x39 made in 1968. But why it is that color I can not tell you.

Nope 7,62x39... but not sure why the entire cartridge is grey...
Steel probably. Need to find a magnet...

 

[Afy]

The bullet is steel... at least magnetic. So guess the entire thingie is painted to prevent rust. Ah well... luckily only have 80 rounds of the stuff.

Looks like steel coated with an epoxy-phenolic lacquer to prevent/delay corrosion. Pretty typical for Commie Block ammo.
