.300 Blackout out of a 16.5 " 1;8 twist Bolt action Remington 783 Heavy carbine barrel is very accurate and has much more velocity at 200-300 yards than the short-barreled pistol with a much tighter shot group. I used this on Feral Hogs and it worked well my friend loaded some Hard Cast lead ammo with a gas check 150 GRAIN flat nose HP for me and it delivered a devastating lethal wound to the Hog. He shoots a 10.5 " AR-15 Pistol and used the Hard cast lead gas check 150-grain flat nose hp bullet at a closer range and it worked well also. But I prefer the longer barrel bolt rifle to the AR-15 Pistol in that caliber, the recoil in very little. With the subsonic bullets and a suppressor on the bolt rifle, the hogs didn't run away when a hog was hit at 100 yards you could hear the bullet hit the hog with a smack 1050 fps Hornady, Subsonic, .300 Blackout, Sub-X, 190 Grain is my favorite round suppressed. I also like the Hornady Custom, .300 AAC Blackout, FTX, 135 Grain, when shooting non suppressed. I have taken several Coyotes, Feral Pigs & Deer with this load with good results.
