How to read it: filled circles are the near and far zero, where the bullet's path crosses the line of sight;the triangle is the peak (max ordinate). The shaded band is the 8" vital zone, ±4" either side of the line of sight. The dashed line marks the edge of the hold-dead-on window. The chart is zoomed to where the zero matters; the tables below run to 400 yards.

Product Overview
Brown Bear's 125-grain SP is a steel-cased jacketed soft point 7.62x39mm load, with no game class named. The lead is left bare at the nose, and at 125 grains it is the heaviest bullet in the caliber. It leaves the muzzle at 2,350 fps with 1,533 ft-lbs, the most of any 7.62x39mm load.
Estimated recoil is the heaviest in the caliber, about 3 percent over the 123-grain soft points compared. The bare lead at the nose puts it with the hunting loads and not the range ones.
If you're cross-shopping, Winchester's Super-X 123-grain SP is a brass-cased soft point, 15 fps faster at the muzzle with 6 ft-lbs less energy. Hornady's SST 123-grain matches this load's muzzle velocity in brass, with a polymer tip over its lead core.
- 25 ft-lbs more at the muzzle than Prvi Partizan's 123-grain PSP and Hornady's SST 123-grain
- 2 grains of bullet more than Winchester's Super-X 123-grain SP and Hornady's SST 123-grain
- A bare-lead soft point, where Red Army Standard's 124-grain FMJ-BT is a closed jacket
- A steel case, which will not reload and is magnetic, so some ranges refuse it. Winchester's Super-X 123-grain SP is a brass-cased soft point
- No polymer tip, where Hornady's SST 123-grain has one
