Return to 7.62x54r Ammunition Introduction


This current production ammunition is made in Bosnia-Herzegovina and is unique as the only light ball soft point on the market.  It is similar to the Privi Partizan ammo as they are both manufactured in ex-military factories of the former Yugoslavia.  The brass case is boxer primed and easily reloadable and this ammunition is a good value in a lighter weight hunting bullet.  According to the Chrony Ballistics II Software used in this evaluation the optimum game weight when fired from an M91/30 is 609 lbs at 100 yards and 320 lbs at 300 yards.  This should be more than adequate for North American deer and antelope.

Funding for this evaluation was provided in part by "BSA" and "Shyquestor" of Gunboards.com.  Thanks to "Springbank" for range assistance.

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.
