.300 Blackout vs 7.62x39mm
The .300 Blackout vs 7.62x39mm comparison examines two intermediate cartridges designed for different roles. The 7.62x39mm (123gr SP at 2,365 fps) produces 1,130 ft-lbs at 100 yards, outpacing the .300 Blackout's (150gr at 1,900 fps) 982 ft-lbs with supersonic loads. Penetration favors the 7.62x39mm at 31.1-31.7 inches compared to 27.8-28.2 inches for the Blackout. Both produce mild recoil: the .300 Blackout at 7.04 ft-lbs and the 7.62x39mm at 8.22 ft-lbs. The .300 Blackout fits standard AR-15 lowers and suppresses well with subsonic loads, while the 7.62x39mm offers cheaper ammunition and proven reliability in AK-pattern rifles.

Self-Defense Ammunition Penetration
Notes:
- FBI standard for optimal penetration is 12-18 inches in 10% ballistics gel
- Our penetration data is calculated using mathematical models based on sectional density, velocity, and expansion factors. While not actual gel tests, our calculations have been validated against manufacturer test data and provide reliable estimates for comparison purposes.
- Actual results may vary depending on clothing barriers and other factors
