The 7.62x39 is a centerfire rifle cartridge, delivering substantial energy on target, which shapes where it fits between varmint work, big-game hunting, and precision shooting. A representative 123-grain loading leaves the muzzle at roughly 2365 fps and carries about 1527 ft-lbs of energy, with a G1 ballistic coefficient near 0.292. Those numbers place it squarely in its intended performance envelope. Based on its energy and trajectory, ethical ranges work out to roughly small game and varmints to about 250 yards; medium game such as deer to about 300 yards; larger game to about 350 yards — always within the limits of your own accuracy and local regulations. Recoil is generally moderate for the class, and our database tracks 1 factory loading so you can compare bullet weights and velocities for your specific use. Figures here are for reference and informational use — always verify against manufacturer data.
