The 300 Blackout (300 BLK) was designed by Remington/AAC to create a reliable, compact .30 caliber round for the AR platform that uses a standard bolt and magazine. .⁠ For those with suppressors, the 1:7 twist favors the heavier subsonic rounds. The very advantage of the 300 BLK (its similarity to the popular .223/5.56 caliber) can also be a safety issue if ammunition of the two calibers is mixed. 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. The numbers make it obvious it’s flatter shooting than the subsonic load. Selecting the best barrel length for the .300 BLK can be a double-edged sword.

Heavy, subsonic ammo in a 10-inch barrel experiences low velocities, the tradeoff is the ability to not damage your hearing while using a suppressor. At 300, holdover is only 23.4 inches. Keep in mind, the odds are good that powder mix completely burns in that 16 inches of test barrel. In the chart, bold-faced entries indicate the last distance at which each Hornady load drops less than 5 feet in different length barrels—for those uncomfortable dialing in or holding over 60 inches.

The 300 BLK was made specifically for ease of conversion, so the standard bolt will work and a magazine can be used to its full capacity, so the only change needed is the barrel & gas system.[16]. Remington Defense was part of the effort, which was no easy task because it included a requirement that it run in standard AR-15 magazines. [citation needed] Modified bolts were also needed owing to its larger case head diameter. Supersonic ammunition muzzle velocities and muzzle energies by barrel length: On the other end of the spectrum are loads that send their bullet traveling faster than the sound barrier.

Supersonic ammo in a 10-inch barrel retains rifle caliber velocities but experiences greater bullet drop at distances. [6], By keeping the M4/M16 in mind as the primary host during load development the designers could work up a host of cartridges that not only satisfied the ballistic requirements set forth, but also ensured mechanical reliability with the fewest changes to the weapon itself—with only a simple barrel change necessary for complete conversion. For an apples-to-apples comparison, the Hornady V-Max 110-grain load (also zeroed at 100 yards through 16 inches of barrel) has a muzzle velocity of 2,375 fps. However, the.300 Blackout round (or 300BLK for short) can serve two roles. .

This is a big advantage as it reduces the weight of the rifle and allows for easier stalking of prey. The bullet has significant drop, drift, and energy loss at that distance. Planes that increase their velocity until it reaches and exceeds that mark generates a sonic boom. Jones, tailored for heavy projectiles that do not break the sound barrier (subsonic), was probably best known at the time and popular enough that the term wildcat does not apply. However, it has the same amount of energy at 700 meters that the M855 has at 500 meters.
