Folks I have a Mauser K98 Preduzece 44 rifle. from what I've been able to find on this rifle is it is a K98 German Mauser that was reconditioned by Yugoslavia. but how do I determine when it was originally made? reason I ask is found a number of forums with data on rifles but separated by WHEN rifle was made and I'm trying to determine some shooting issues I'm having? when shooting 8mm Prvi-Partizan 196gr SP ammo rounds hit low and left while the military FMJ (unknown brand/gr?) shoots high which seems to be the norm from what I've read? Any ideas?
