This ammunition is repackaged in the former Yugoslavia.  Based on the condition of the cases it appears to have been cleaned by tumbling and the primers replaced and sealed.  Ammunition of this era would not have had sealed primers.   Ignition is reliable and consistent and the ballistics are surprisingly good for something of this vintage, although it should probably be classified with the newer production surplus since it has been "reworked".

Trajectory and Drop Graph (click on the thumbnails)
Notes on the graphs  The graphs above each represent two sets of data.  The red line is the path of the bullet fired from the rifle with the sights zeroed at 200 yards.   The bullet exits the muzzle at a distance a fraction of an inch below zero inches.   This represents the height of the sight over the centerline of the bore.  The bullet rises above zero in a trajectory that then passes through zero again at 200 yards and continues downward.  The blue line is the the bullet drop in inches for the distance traveled.  This begins at the muzzle at zero inches and decreases with distance not taking sight height or zero distance into account.
