It doesn't look like the captive piston cartridges I'm familiar with.
Edited to add: from a European source of mine, these cartridges are meant to sabotage the weapon they are fired in. The projectile is designed to lodge in the bore so that when the next round is fired it ruptures the barrel. Known in 7.62x39mm, 5.45x39mm, and 9x18mm Makarov. They are called "Iskra" (Spark in Russian) self destruct cartridges. Reportedly introduced by Russia during the Chechnya-Russia conflicts. The portion of the projectile behind the copper colored "jacket" is hardened steel and the grooves are designed to cut into the rifling, lodging the projectile in the bore. In researching this, I've found both 7.62x39mm and 5.45x39mm versions made by "539" (Tula) in the early to mid 1990s.
