Solved at standard sea-level atmosphere (59°F, 29.92 inHg) with a 100 yard zero, 1.75" sight height and a 10 mph full-value crosswind. Drop is relative to your zero.

Quick answer

With a 100 yd zero, a 123 gr SST hunting 7.62x39mm load (123 gr, 2350 fps) drops 2.0" at 150 yd, 13.3" at 250 yd and 103.1" at 500 yd. Change the load or zero above to see your own numbers.

7.62x39mm trajectory

The 7.62x39mm launches a 123 grain .311 caliber bullet around 2,350 fps — nearly identical to supersonic .300 Blackout and .30-30 inside 200 yards, with rapid drop past 250.

Flat-base 123 grain FMJ and soft-point bullets shed velocity fast; zero at 100 or 200 yards and measure actual velocity from your barrel length before stretching past 250.

Frequently asked questions

With a 123 gr SST hunting load at 2350 fps and a 100 yard zero, a 7.62x39mm drops about 23.3 inches at 300 yards (7.4 MOA / 2.2 MRAD), and about 6.4 inches at 200 yards. The full chart above covers every range and load.

A typical 123 gr SST hunting load leaves the muzzle at 2350 fps with 1509 ft-lbs of energy. At 300 yards it is still moving 1589 fps and carrying 689 ft-lbs. These figures are solved from the load data, not copied from a box chart.

A steady 10 mph full-value crosswind pushes the 123 gr SST hunting load about -14.7 inches at 300 yards. Wind drift grows faster than drop with distance, which is why wind reading matters more than memorizing holdover.

This 123 gr SST hunting load stays supersonic to at least 400 yards under standard conditions. Accuracy degrades through the transonic band (roughly 1,340 fps), so treat that as the practical ceiling for predictable precision. Terminal effectiveness on game depends on the energy column above — most hunters watch for 1,000 ft-lbs on deer-class animals.

Your barrel length, actual muzzle velocity, and the day’s density altitude all shift the solution. These tables use standard sea-level atmosphere and published velocities. Chronograph your load, solve for your real conditions, and true the result against actual impacts — the Atlas Ballistics app does all three.
