I have a buddy that downloaded a bunch of the yugo 8mm that was way too hot (I forget the year of that batch but I think it was '53 or '54) and had excellent luck. It quit flattening primers and splitting cases and turned into really good shooting ammo. I forget his exact formula but if your going to down load milsurp I'd pull the bullet, weigh the charge and start out by reducing it 10%. This will usually be somewhere between 4 and 5 grains. If you have access to a chronograph, shoot some of it and work up from there. I know this may go against the grain or many, but I have seen it work well. I have shot a bunch of the Romainian light ball in my '93's and Gew 88's with no problems at all. It doesn't seem to be anywhere near as hot as the Turk or the Yugo. Good luck.
