125 grain Nosler Ballistic Tips and 125 grain Hornady SST bullets are also a great 300 Blackout solution. I’ve also has near perfect success with Sierra MatchKing bullets in 125 and 135 grain weights. It’s on the lighter side of the range of 300 AAC Blackout bullets, so it’s intended for the higher end supersonic performance. The Barnes TAC-TX is a perfect example of a projectile designed specifically for the 300 AAC Blackout. Not the long skinny profile for magazine feeding reliability. This Barnes TAC-TX 110 grain projectile is made specifically for 300 AAC Blackout. If they are too large in diameter at the position of the magazine ribs, feeding can also be impacted. If the bullets are too short, feeding can be problematic. Generally speaking, long, pointy bullets seem to work best. Since the 300 AAC Blackout uses a cut down case, the ribs will be supporting the bullet itself, so the projectile has to be consistent with the expected dimensions, else feeding reliability will suffer. 223 magazines are sized to support the necks on. First, you need to find projectiles compatible with. To narrow things down, lets talk about ideal projectiles and powders. I’ve only recently started tinkering with 300 Blackout loads and have already loaded and tested over 40 different projectile, powder and charge combinations, and I’m just getting started. With the broad range of bullet weights and velocities, you may never settle on your own standard load. There’s entirely too much tinkering potential. If you reload ammunition, getting a 300 AAC Blackout rifle may very well ruin your family life. The one missing from this photo is Accurate 1680 which is an excellent all around solution for 300 Blackout. Some of the powders I’ve used in both super and subsonic 300 AAC Blackout loads. If you look at the trajectory of a 220 grain Sierra MatchKing fired at 1,023 feet per second, also zeroed at 50 yards, you’ll see the following.ģ00 AAC Blackout 220 Grain Sierra MatchKing, 2,350 fpsĬlearly the subsonic loadings are not intended for long range use, although it might serve as an exceptionally lightweight mortar. But it’s insanely cool, quiet and useful at ranges of 100 yards or less. When it comes to subsonic performance, the 300 AAC Blackout has no direct competitor. 223 Remington projectile traveling at 3,240 feet per second.ģ00 AAC Blackout 110 Grain Barnes TAC-TX, 2,350 fps. On the supersonic side, let’s compare bullet drop of a “300 Blackout specific” projectile like the Barnes TAC-TX 110 grain bullet to a 55 grain. We’ll consider scope adjustment for a 50 yard zero range using an optic that is 2.5 inches above the bore. We’ll talk about that in detail next week. Of course, all of these options will have incredibly diverse trajectories, and that’s what gives scope makers fits over the 300 AAC Blackout. How about a 208, 220 or even 245 grain projectile moving at 1,000 feet per second or less? Or you can get crazy and go full subsonic from the same AR platform rifle. You can get something in the 150 to 168 grain range that will move in the 1,700 to 2,000 feet per second range. Feel like something more moderate? No problem.30 caliber bullets are available in all weights. Buy some 100 or 125 grain ammo that will move along at up to 2,400 feet per second. We’ve already hinted at the incredibly broad range of bullet weight and velocity that can be successfully fired from the same gun. It’s a great option for a 300 Blackout rifle. It features a calibrated ballistic compensation reticle for supersonic and subsonic rounds. I used the Leupold Mark 4 MR/T 1.5-5×20 scope for all accuracy testing. When it comes to recoil energy, assuming you’re using an 8 pound rifle, the Blackout hits you less with 4.3 foot-pounds compared to the AK’s 6.34 foot-pounds. The 110 grain Blackout at 2,375 feet per second yields 1,377.4 foot-pounds of muzzle energy to the AK’s 1,650.8 at 2,600 feet per second. If you do a rough comparison of muzzle energy of the 300 AAC Blackout to the 7.62×39 (AK-47) round, you’ll see a slight edge to the AK with a 100 grain bullet. In that book, you can compare pretty much anything about any cartridge to anything else about any other cartridge. He likes both topics so much that he wrote the Cartridge Comparison Guide. He apparently did get physics and he really likes guns. So when it comes to looking at cartridge energy and recoil figures, I always rely on my friend Andrew Chamberlain. I made it through, but I never really understood concepts like acceleration, momentum and why mass is different than weight. I’m a professional goofball, so I never really got physics. 223 Remington load is shown on the far left for scale. Celebrate diversity! 125, 245 and 220 grain projectiles, left to right.
