300 AAC Blackout

.300 AAC Blackout 110 Grain Hornady V-Max- The .300 AAC Blackout (designated as the 300 BLK by the SAAMI and 300 AAC Blackout by the C.I.P.), also known as 7.62×35mm is a carbine cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. Its purpose is to achieve ballistics similar to the 7.62×39mm Soviet cartridge in an AR-15 while using standard AR-15 magazines at their normal capacities. It can be seen as a SAAMI-certified copy of J. D. Jones’ wildcat .300 Whisper. Care should be taken not to use 300 BLK ammunition in a rifle chambered for 7.62×40mm Wilson Tactical.

Robert Silvers, director of research and development for AAC said, “We started development in 2009, but most of the work was done in 2010. A military customer wanted a way to be able to shoot .30-cal. bullets from an M4 platform while using normal bolts and magazines, and without losing the full 30-round capacity of standard magazines. They also wanted a source for ammunition made to their specs. We could not have just used .300-.221 or .300 Whisper because Remington is a SAAMI company, and will only load ammunition that is a SAAMI-standard cartridge. We had to take the .300-221 wildcat concept, determine the final specs for it, and submit it to SAAMI. We did that, and called it the .300 AAC Blackout (.300 BLK).”

300 AAC BLACKOUT was approved by SAAMI on January 17, 2011.

The Bullet:

Hornady V-Max Bullets feature a polymer tip which enhances accuracy and promotes devastating expansion. The tip raises the ballistic coefficient for faster velocity and also acts as a wedge, initiating bullet expansion. The flat base creates in-flight stability for long-range shooting.

Hornady’s swaging process creates precise formation of the core around the tip of the bullet, creating a build-up of energy which contributes to its phenomenal performance.
