Because the cartridge uses a large bullet and has limited case space for powder, the bullets tend to shed velocity more quickly than other. These are good for special ops work and hunting.Īll 300 BLK bullets start out with decent velocity: 110-grain bullets crank out of the muzzle at 2,350 fps. Lightweight 78-grain bullets are designed for close-quarters defense, while at the opposite end of the spectrum are 220-grain bullets loaded for subsonic velocities and designed for use with a suppressor. Not a hunting bullet by any means, but it’s an excellent example of the accuracy you can expect from the 300 BLK.Īs seen here, the Hornady GMX expands and penetrates plenty to handle most medium-size game, such as deer and hogs.Īvailable bullets range in weight from 78 to 240 grains depending on the application. When I tested a Windham Weaponry RMCS-4 rifle in 300 BLK, my smallest group measured 0.28 inch with Sig Elite 125-grain Sierra Match King bullets. Even though the round was designed for combat and defensive scenarios, and not specifically for hunting medium-size game, it offers excellent performance if kept within its range of effectiveness. The 300 BLK was designed to provide ballistics similar to the Soviet 7.62x39mm cartridge in the AR-15 platform, as well as perform at super and subsonic velocities. The reason for this is the original 300 Whisper wildcat cartridge was designed to use lightweight bullets at supersonic velocities and heavier bullets at subsonic velocities. The 300 BLK cartridge itself is odd-looking, like too much bullet was stuffed into too little a case. At the range and through AR-15 platforms, I could easily shoot groups with match ammo that were sub-MOA. Now that more factories are producing a variety of loads - both supersonic and subsonic - I was all in. OK, I admit it: I was getting jazzed.Īfter using the 300 BLK at the range, I started to like it even if there were not that many ammunition manufacturers producing 300 BLK ammo at the time. 30-caliber bullet and was specifically designed to fit in the AR-15 platform. What I liked about the 300 BLK cartridge was that it used a. caliber, which is the caliber typically associated with the AR-15, is effective on wood chucks, ground hogs and coyotes - not game animal taller than knee high. That appreciation did not come quickly nor easily because the 5.56 NATO/.223 Rem. While the AR-15 platform is about as far away from a Marlin or Winchester lever gun as you can get, I appreciate the AR-15 platform as a hunting rifle. That caliber also helped me better understand trajectory in relation to bullet weight and velocity. ![]() Silence doesn’t spook deer, and a correctly placed shot leads to less tracking and more dragging. I learned to hunt white-tailed deer by silently cocking back the hammer of a lever-action rifle and knowing the limitation of the. ![]() Simply stated: We have peace of mind with. We deer hunters really like calibers that use. 30-caliber bullet, I start thinking in terms of deer, and how the cartridge and bullet combination will work for hunting deer. What started my curiosity with 300 BLK was the. Hornady’s 110-grain GMX, which comes loaded in the manufacturer’s Full Boar ammo, is something the author recommends as a 300 BLK hunting load. The fact the cartridge is offered in supersonic and subsonic loads also confused some hunters. Most manufacturers of the cartridge have settled on calling it the 300 BLK. The 300 Whisper is considered the progenitor to the cartridge. The short answer is that they are basically all the same cartridge with different names. Was it the 300 AAC Blackout, or was it the 300 Whisper? Maybe the 7.62x35mm? Isn’t it the 300 BLK? I was very confused about what the 300 AAC BLK was. And you can see that was part of my issue. Not that the 300 AAC BLK was actually new by then, it was less of a wildcat cartridge than the 300 Whisper. When the 300 BLK became a made cartridge by Advanced Armament Corp (AAC) and Remington after being blessed by SAAMI in 2011, there was a lot noise and chatter about the launch of the new cartridge for the AR-15 platform. ![]()
