Las Vegas, NV – Staff Sargent Daniel Horner of the US Army’s Marksmanship Unit used the new 300 AAC Blackout cartridge to win 1^st overall in the Tactical Optics division of the 2011 USPSA Multigun National Championship, held outside of Las Vegas, Nevada.

300 AAC Blackout was launched by Advanced Armament Corp. and Remington as a military cardtrige. The concept is to enhance precision and lethality by using a 30 caliber bullet fired from M4/AR15 platform;using standard magazines. However, both Remington and AAC expect to see a lot of use for hunting, plinking, and home defense as well. The concept of putting a 30-caliber bullet in a shortened 223 case has been done before, but not as an industry-wide standard that anyone can make products for, royalty-free.

SAAMI, the industry standards organization, adopted the 300 BLK earlier this year, and it now has broad industry support with over 60 companies manufacturing products for it.

Remington is leading the pack with the most types and highest volume of ammo available; 125 grain open-tip match with a custom Sierra bullet; 220 grain subsonic and a 125 grain AccuTip for hunting, law enforcement, and self-defense.

While this is one of the lowest-cost cartridges to reload, Remington and AAC recognized that most people are not reloaders, so UMC ammo is planned to be out soon with a price of just $12.99 MSRP per box – substantially less than other cartridges that are a power upgrade from 223. And the use of the cartridge to win the Nationals while qualifying for “Major Power Factor” leaves no doubt about the potential for accuracy and the capability of some major punch.
