![]() With that change they found in their gel tests the initial wound cavity increased by two times. The Q engineers began testing with a 1:10 twist and then went to a 1:7 twist. An 8.6 BLK rifle will have a 12- to 16-inch barrel with a 1:3 twist rate (much faster twist rate than a typical rifle).Īccording to Brittingham, increasing the rotational velocity increased muzzle velocity and helped subsonic bullets expand. 308 hunting rifle has a 22-inch barrel with a 1:10 twist rate. Twist Rate and Barrel Length Fast twist rates are one of the keys to the 8.6 Blackout’s lethality. But at least for now, Brittingham’s claims are impressive. Of course, we won’t know the true accuracy potential of the load until we (and others) get to range test it. “I’ve killed four Cape buffalo with supersonic,” Brittingham says. The supersonic ammo is best for big game and shooting to 500 yards, however Brittingham says he plans to test the subsonic on big, dangerous game, too. He’s already put several Cape buffalo down with supersonic loads. “I shot one at 207 yards and he went 30 or 40 yards,” he says. Zebras are surprisingly large, tough critters, but that animal only went 30 yards after a broadside shot. ![]() 300 Blackout obsolete for hunting honestly.”īrittingham’s first animal with subsonic 8.6 BLK was a zebra, which he shot at 30 yards. “With some subsonic loads we’re getting 1 MOA at 300 meters, which is where we think the max is for subsonic hunting,” Brittingham says. The 8.6 Blackout was designed to be used for hunting with both subsonic or supersonic ammunition. Utilizing heavier bullets and faster rifling twist rates (more on this later) it was also designed to outperform. To give you the ability to shoot big animals with short barrels and lightweight guns.” Hunting Applications 8.6 Blackout (left) and. “That’s always exciting to us, but we really wanted to do something for the commercial market for hunting. “It started as a joint project with a foreign military, and some of our special operations groups are now involved with it,” Brittingham says. 300 Blackout whether its barrel twist or bullet design, we put into this.” Basically every lesson that we learned from. “The idea with the supersonic loads is to get magnum cartridge capabilities from a standard pressure cartridge in a lightweight gun,” he says. “We wanted a cartridge that could work in a compact, lightweight gun with a short barrel and could shoot supersonic or subsonic out of bolt guns or gas guns.” “I think it’s the best utility cartridge ever developed,” Brittingham says. 300 Blackout with better terminal performance. Brittingham says the subsonic loads are just as quiet as. The length of the case centered around fitting in an SR25 magazine.īullet weights for 8.6 Blackout range from 155 to 350 grains, and velocities range from around 2,400 fps to around 1,000 fps. “We settled on shortening up the 6.5 Creedmoor case because it’s a little more efficient than the. It can be shot at super and subsonic velocities. 338-inch-diameter bullet in a shortened 6.5 Creedmoor case.
