I don’t know anything about 8mm ammo and I found this amongst a collection of 7.62x51mm that I got recently and I was wondering what it is as the tip has a slight hollow in it.
h/s: DAG 55
Annuals Colour: Green
Case mouth colour: Green
There appears to be a printed ink stamping on the side of the case (very faint) " (something) 8x57 JS "
