You should expect a muzzle velocity of around 1,000 fps for most 8.6 Blackout ammo, including the Gorilla Subsonic Hunting 8.6 Blackout 342-grain Pork Shredder CHP. However, the Gorilla 8.6 Blackout 210gr TSX has a much higher-than-usual muzzle velocity of 1,970 fps.
The 8.6 Blackout is designed for barrels using a 76 mm or 102 mm (1:3 in or 1:4 in) twist rate and bullet weights between 10.4–14.6 g (160–225 gr) for supersonic loads and 18.5–22.7 g (285–350 gr) for subsonic loads.
Apr 17, 2024 · A 350-grain subsonic bullet in the 8.6 BLK produces around 830 ft-lbs of energy compared to the .300 BLK’s 200-grain bullets that produce only 490. Supersonic energy for the 160- to 210-grain 8.6 BLK bullets will be around 1,800 to 2,000 ft-lbs.
Jan 6, 2024 · This 8.6 Blackout article provides ballistic graphs (energy, trajectory, velocity, and recoil) of the new wildcat cartridge (subsonic and supersonic) and how they compare to mainstream cartridges including its main rival – the 300 Blackout.
Jan 30, 2024 · In essence, 8.6 Blackout is designed to shoot heavy .338 caliber bullets at modest supersonic or quiet subsonic speeds for hunting or self defense. The cartridge is unique for its radical 1:3 twist rate which produces extreme rotational energy to aid its terminal performance and allows it to shoot accurately with subsonic ammunition.
Welcome to the 8.6 Blackout journey —a testament to their quest for ballistic excellence. What is 8.6 Blackout. The 8.6 BLK round was imagined and developed by Q. When imagining 8.6 Blackout, a good starting point is to think of 8.6 BLK as the big brother to 300 Blackout. However, it’s much more than just an upgrade on 300 BLK.
Dec 3, 2022 · The length of the case centered around fitting in an SR25 magazine. Bullet weights for 8.6 Blackout range from 155 to 350 grains, and velocities range from around 2,400 fps to around 1,000 fps. Brittingham says the subsonic loads are just as quiet as .300 Blackout with better terminal performance.
