The 7.62x39mm, also known as 7.62 Soviet or M43, is a rimless bottlenecked intermediate cartridge developed by the Soviet Union in 1943 for use in the SKS rifle and later the AK-47. It was designed to provide reliable performance in automatic weapons, balancing power and controllability for military applications. This caliber has become popular worldwide for hunting, target shooting, and defense due to its affordability and versatility in both supersonic and subsonic loads. This article focuses specifically on ballistics, analyzing external factors like bullet drop, wind drift, and energy retention, as well as wound ballistics for practical terminal performance. Both supersonic and subsonic loads will be examined to give reloaders and hunters a clear understanding of how this cartridge behaves in real-world scenarios. For more on the cartridge specs and reloading tips, check our 7.62x39mm guide. Compared to similar rounds, see the 7.62×39 vs .300 Blackout comparison or 5.56 NATO vs 7.62×39 comparison.
Core External Ballistics
The 7.62x39mm uses different bullet weights and velocities, with supersonic loads (typically 123-154 grains at 2300-2400 fps) offering decent trajectories for hunting and defense, while subsonic loads (around 200 grains at 1050 fps) prioritize quiet operation with suppressors. Supersonic rounds behave like intermediate rifle cartridges with solid energy transfer, but subsonic ones drop quickly due to lower velocities. Data sourced from major manufacturers shows significant differences in performance beyond 300 yards. For deeper charts, refer to our .308 Winchester ballistics for comparison, or the caliber selection guide.
Bullet Drop to 1000 Yards

These numbers, based on a 100-yard zero, illustrate the 7.62x39mm’s limitations at long range. Supersonic loads like the 123gr remain practical to 300 yards for hunting, with manageable drop for ethical shots on deer or hogs. Beyond 400 yards, the trajectory arcs sharply, making hits unreliable without precise holdovers. Subsonic loads drop dramatically after 200 yards, limiting them to close-range suppressed applications. Realistic ranges for hunting are 250-300 yards supersonic and under 150 yards subsonic. The caliber’s ballistic limitations begin around 300 yards for precision work. For comparisons, see our 6.5 Grendel ballistics or .308 vs .30-06 comparison.

Heavier supersonic bullets like 154gr resist drift better at short ranges due to mass, but their speeds increase time-of-flight, amplifying drift beyond 300 yards. Subsonic loads show more drift overall due to slower velocities. Practical accuracy diminishes after 300 yards in windy conditions, where reading gusts becomes unreliable. For supersonic shooting, expect consistent hits to 250 yards; subsonic is best under 150 yards. See our varmint caliber guide for wind-related tips.

Energy decays faster in supersonic loads due to air resistance, dropping below 500 ft-lbs by 500 yards, while subsonic starts low but retains better proportionally. Ethical hunting ranges are 300 yards for supersonic on medium game, where energy supports expansion; subsonic fails to expand reliably beyond 100 yards without specialized bullets. Certain loads lose effectiveness at distance due to velocity thresholds. For more, review our long-range calibers guide.
Terminal & Wound Ballistics
Bullet design is crucial in 7.62x39mm, as supersonic loads create hydrodynamic shock for rapid incapacitation, while subsonic rely on expansion and penetration for effective wounds. The goal here is to provide practical guidance on terminal performance for hunting and defense. For gel-testing insights, explore our bullet reviews.

Practical Summary
For predators like coyotes, the Hornady V-MAX in supersonic loads fits best with its explosive fragmentation. For hogs and deer, opt for Barnes TTSX, Nosler Ballistic Tip, or Remington Core-Lokt supersonic for penetration and expansion. Subsonic suppressed use shines with heavier bullets like soft points, providing quiet, effective terminal results under 150 yards. Range discipline matters greatly, as the 7.62x39mm loses energy quickly beyond 300 yards supersonic. Bullet choice defines terminal results more than velocity alone, especially in subsonic where expansion is key. To dive deeper, read our big game caliber guide or AR-15 barrel guide.
