I had one of those; 1939 Romanian. It was kind of a beater and the bore was maybe 65% but it still shot really well.
Its hard to beat the 8mm Mauser! My first milsurp was a Yugo M-24/47 (pretty much the Yugoslavian version of your's). I loaded some 200 gr. Speer Hot-cors and took her hunting. My first prey were two Barbado rams. Shot clean through both of their shoulders with one bullet at 125 yards. Needless to say, I was sold on the 8x57!
Most milsurp 8x57 like the longer, heavier projectiles. 200 grain are a beast!
