I would just stick with loads that mimic 7.62 NATO ball ammo. The 150-grain Hornady FMJ's are cheap in bulk quantity and shoot a lot better than most GI and surplus ball bullets I've seen. From Hodgdon's data, IMR 4895 at about 45.4 grains should be close on ballistics, but start with Hodgdon's 42.6 grains starting load and work up. 47.4 grains of BL-(C)2 would also mimic GI ballistics pretty simply, but, again work up from the starting load of 45.0 grains.
