I dont shoot surplus ammo, I shoot sellier & bellot czech 196 grain FMJ through it with EXCELLENT results! Its clean, its good quality, its not corrosive, its loaded to full spec (196 @ 2600 fp/s) and it is very accurate. the brass is also very good.
Not long age I shot 5 shots at .84 at 50yds with my 98k with very good bore and muzzle.
