The Idea Behind .300 Blackout (BLK)
The main idea behind .300 BLK is:
- To be capable of shooting subsonic and supersonic ammunition out of the same firearm with no problems.
- To enhance the performance of the AR15/M4 platform with regards to muzzle energy.
AAC based on the typical .300 BLK of the .223 / 5.56 NATO case. It means that only a barrel swab is needed to turn an AR15 to this caliber. All other parts remain the same because the .300 BLK’s parent case is the .223 / 5.56. AAC decided on the supersonic loads with all these modifications. Their supersonic loads trigger 110 to 130-grain bullets at velocities, similar to the Russian 7.62X39mm that’s fired by the AK47.
Performance of .300 Blackout
The .7.62 cartridge taper of the Soviet hindered good feeding in the standard AR magazines. They also led to wear on the bolt. The M855 5.56X45mm round has a good point target range of 500 meters. The bullet also has much drop, drift, and loss of energy at this distance. A 125 gram 300 BLK round has less velocity. It has a similar bullet drop and drift at fewer distances. But note that its amount of energy is the same at 700 meters as the M855 at 500 meters.
Regarding hit probability, Blackout’s range is 460 meters. The 125 gram BLK round with 230 mm barrel has the exact muzzle force as the M855 from M4. It also has 5 percent greater energy at 440 meters. The 300 BLK rounds with differing loads have more ballistic coefficient and power from barrels with similar lengths. The 300 BLK rounds possess the ‘barrier blind’ performance. It means that they can penetrate through many inches of varying hard targets. 300 BLK also enables the users to possess one firearm and can switch between subsonic, supersonic, or barrier penetrating ammunition. It happens with a simple modification of a magazine.
A single shot rifle or bolt action in this caliber makes .300 BLK an excellent small to medium range deer hunting cartridge. It has less costly ammunition components and minimal recoil, which are both good things. Brass can easily be created from plentiful and less pricy .223 / 5.56 cases by cutting off the necks under the shoulder and then running them on a .300 BLK sizing dye.
