Yeah.. I think my reloading data states 'russian' after the caliber aswell.
Well it ain't 7.62x39 Springfield, Mauser, Ackley Improved, Winchester Magnum, WCF, Long Rifle, Swede, Swiss, French, Sharps, Tokarev, Luger, Rimmed, Carcano, Kurtz, T-Rex, Weatherby, Long Colt, Smith and Wesson, Colt, Krag, NATO, Government, British, Jap, Parabellum, Marlin..........
So why not call it Russian? It's Mother Russia's baby..
