.300 BLK (Blackout) Ammo

The .300 AAC Blackout, commonly known as the .300 BLK or 7.62x35mm, is a versatile and efficient centerfire rifle cartridge developed by Advanced Armament Corporation (AAC) in collaboration with Remington Arms. Introduced in 2011, the .300 BLK was designed to offer enhanced performance and compatibility with the AR-15 platform, providing a reliable and powerful option for military, law enforcement, and civilian applications, including suppressed shooting, hunting, and self-defense.

The .300 BLK features a rimless, bottlenecked case and utilizes a .308-inch (7.62mm) diameter bullet. The cartridge is designed to work with standard AR-15 magazines and bolts, requiring only a barrel change to switch from the more common 5.56 NATO/.223 Remington. The .300 BLK offers a wide range of bullet weights, typically between 110 and 220 grains, with muzzle velocities varying from 1,000 to 2,400 feet per second, depending on the specific load and bullet weight.

One of the primary advantages of the .300 AAC Blackout is its ability to function efficiently with both supersonic and subsonic ammunition, offering enhanced versatility and performance in a wide range of scenarios. Supersonic loads provide improved terminal ballistics and extended range capabilities, making them suitable for hunting medium-sized game and self-defense applications. In contrast, subsonic loads, when paired with a suppressor, offer reduced noise and muzzle flash, making them ideal for tactical and stealth applications.

Factory-loaded ammunition for the .300 BLK is available from various manufacturers, offering a variety of bullet types and weights to suit different applications, from hunting to suppressed shooting and self-defense. Additionally, handloaders can find an extensive selection of .308 caliber bullets, brass, and reloading data to customize their ammunition according to their specific needs and preferences.

In summary, the .300 AAC Blackout is a versatile and efficient cartridge that provides AR-15 platform users with a reliable, accurate, and powerful option for various applications. Its compatibility with both supersonic and subsonic ammunition, as well as its performance in suppressed shooting scenarios, have earned it a place among the popular and innovative cartridges in the modern firearms market.
