.300 Blackout vs 5.56x45mm NATO
The .300 Blackout vs 5.56x45mm NATO comparison covers the two most popular AR-15 calibers. The 5.56 NATO (55gr at 3330 fps) shoots flat with only 39.4 inches of drop at 500 yards, while the .300 Blackout (150gr at 1900 fps) drops 142.4 inches. Energy at 300 yards measures 798 ft-lbs for the 5.56 versus 650 ft-lbs for the .300 Blackout. Both produce mild recoil under 8 ft-lbs. The 5.56 reaches farther and costs less per round for training. The .300 Blackout hits harder at close range, works with subsonic loads for suppressed shooting, and uses standard AR-15 magazines. Both use the same bolt carrier and lower receiver. Performance varies with ammunition selection and barrel length.

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
