History of Bulk 300 AAC Blackout Ammo

Advanced Armament Corporation developed the .300 AAC Blackout in 2010. The .300 AAC's noise is drastically reduced with the use of subsonic loads and a suppressor. Coupled with a bullet about 40 percent heavier than the 9mm fired from the MP5-SD and moving nearly 100 feet per second faster, the .300 Blackout dramatically outperforms the previous gold standard.

    Bought this ammo for a Run N Gun competition, it worked falsely as it should. I reload my own but with the short notice of this shoot I did not have the time to reload my own. I have some to trust Hornady products as I use there Lock N Load AP Ammo plant press. This ammo was great and was super quiet with my 10.5" SBR I will be getting some more soon so I have the brass to save this time.
