What can you tell me about the origins of this 7.62x39mm cartridge? Appears to be re-manufactured with a confirmed M-43 projectile, but why the added cannelure? Soviet head stamps from 3, 17, and 60, early 1970’s dates. Sold in the US from a Gun Broker listing. Came in a 500 round box with no markings.
