.300 Blackout vs 8.6 Blackout
Part of our full caliber comparison chart — energy, drop and recoil for every rifle caliber side by side.
The .300 Blackout vs 8.6 Blackout comparison matches two subsonic-capable AR cartridges with vastly different power levels. The 8.6 Blackout (210gr TSX at 1970 fps) delivers 682 ft-lbs at 500 yards, well above the .300 Blackout's (150gr Polymer Tip at 1900 fps) 446 ft-lbs. Both cartridges drop steeply at range: the .300 Blackout falls 142.4 inches at 500 yards versus 129.9 inches for the 8.6. Recoil doubles with the 8.6 at 14.1 ft-lbs compared to the .300 Blackout's 7.0 ft-lbs. The .300 Blackout runs in standard AR-15 lowers, while the 8.6 requires an AR-10 platform. Both excel suppressed, but the 8.6 offers big-bore terminal performance. Performance varies with ammunition selection and barrel length.
