Our first load with the 110 Vmax was 19 grains of Winchester 296 and Winchester primers. I worked up some light weight bullet loads for the 300 AAC with the Hornady 110 gn Vmax. Of course, under recoil, there was a possibility that something could be wrong internally, but we would have to do some shooting before we could determine that.
The scope has target knobs and they seemed to track very well and could find no obvious problems with the scope. We checked all the mounting screws and re-positioned the scope a little farther to the rear to get a little better sight picture before we started any testing. This combination should be great for a hunting rifle. Fred’s scope for the rifle is a Nikon P300BLK 2×7 with BDC reticle designed for the 300 AAC Blackout, and the mount was a Burris P.E.P.R. The first couple of things we wanted to do was to give the rifle barrel a thorough cleaning and then check the scope mounts and and the scope itself to see if anything was wrong with it. Remington UMC 300 AAC Blackout is non-corrosive, new production ammunition in boxer primer and reloadable brass cases. My results confirm that to be true over my 200 yard test range. These Open Tip Match bullets are designed with small meplat in order to achieve the highest ballistic coefficient possible. This Remington UMC 300 AAC Blackout is loaded with a 120 grain Open Tip Flat Base bullet to about 2200 fps. We opted for some of the Remington Supersonic 120 grain loads for our range test. I visited my local Academy Sports and found ammo by Remington, Federal, Barnes, Sig Sour and the Academy Store brand ranging in bullet weights from 110 grain varmint loads to 220 grain sub-sonic. After all the work was done, the military never adopted the 300 Blackout, but it has become very popular with hunters who like the AR15 platform, especially for hog and deer hunters.ģ00 Blackout ammunition is relatively easy to find. These larger, heavier bullets also penetrate hard surfaces like vehicles better than the smaller 223 bullets.
The 300 Blackout met the power needs of the military, and also gave them a very good sub-sonic cartridge using heavy bullets with suppressors for Special Forces operations. The bolt and magazines were the same for the 300 as the 5.56 NATO. An advantage to the 300 Blackout is that to convert an M4 to 300 Blackout, only the barrel has to be changed out. The Army needed more power from their M4 carbine at longer range – power similar to or better than the of the 7.62×39 rounds that were coming at them from AK47’s.Īdvanced Armament Corporation (AAC) was one of the companies that tried to develop a cartridge to fill the bill along with several other companies and cartridges like the 6.8 SPC and the 6.5 Grendel. His needs were similar to the military’s needs when the cartridge was designed. 300 Blackout – Power For AR15 Hunting Needsįred wanted the 300 Blackout for more power for larger game than the Remington 223 delivers from his AR15 rifle. Our goal was to find a good hunting load for the 300 AAC Blackout using factory ammunition and handloads suitable for hogs and predators. After trying several brands of ammo and several bullet weights from 110 grain to 220 grain with disappointing results, we decided to start over at square one and try some new hand loads and some of Remington’s new 120 grain supersonic ammo. He was not looking for sub-moa performance, but he was expecting good hunting accuracy in the 1-2″ range. This same rifle using the 5:56 NATO upper assembly shoots sub-moa groups with no problems, so he expected good accuracy from the 300 as well.
My hunting buddy, Fred had been trying to come up with good, consistent load for hunting hogs with his Daniel Defense DDM4V5 rifle in 300 Blackout caliber. Our 300 AAC Blackout range test started out from frustration.
