Not to split hairs here, but all of the military surplus 5.45 (except for the Bulgarian, Polish and East German) is not Russian, it was made in the Soviet Union. The fact that some of it was made at the Soviet run factory in Ukraine is irrelevant. No matter where the ammo was made in the Soviet Union, it was all made to the same specifications. To think that ammo was only stored and used in the republic that it was manufactured in makes no sense. All of the Soviet factory codes in 5.45 have turned up in Afghanistan (7, 17, 60, 270 and 539), including the "270 76" code on the currently available surplus. The real question is why has only "270" and "539" ammo from 1976 turned up so far as surplus?
