300 Blackout Ammo

One of the most popular alternative chamberings for the AR-15 platform, .300 AAC Blackout ammo is easily distinguished by its relatively small case and huge bullet. This somewhat odd-looking cartridge fulfills a number of niches better than the default .223/5.56 caliber with better close-range performance and excellent potential in suppressed firearms.

.300 Blackout ammunition comes in two distinct flavors: subsonic and supersonic. Supersonic loads typically fire a light 90-130 grain bullet at a muzzle velocity of around 2,200 feet per second with ballistics comparable to those of the Russian 7.62x39mm. Subsonic ammo, on the other hand, fires a much heavier bullet in the 220 grain range with a muzzle velocity of around 1,000 feet per second to avoid the sonic "crack" that partially negates the advantages of a suppressor.

The .300 AAC has been embraced for a wide variety of purposes, with hunting, match, and defense loads available from most manufacturers including Nosler, Federal, and Corbon. Notable adaptations of the round include Remington's Hog Hammer series featuring Barnes TSX copper bullets as well as Hornady's Zombie-Max hollow point series for those prepping for the undead apocalypse - you can find a wide variety at cheap prices for sale here at Widener's.

    Excellent choice

    Used about 180 rounds of this at a 4 day rifle class at Front Sight. Worked perfectly. Chrono'd 10 rounds when I got home, averaged 2300 fps. Affordable and quality ammo...

    If you're looking for an inexpensive supersonic load for your .300 AAC AR-15 or other rifle, this ammunition from Sellier & Bellot has you covered.

    These cartridges come in boxes of 20 and fire a 147 grain full metal jacket bullet. While the use of a light bullet gives up some noise reduction advantages in suppressed rifles, it also produces flatter trajectories and better medium-range ballistics.

    Sellier & Bellot ammunition is loaded in the Czech Republic using non-corrosive primers and reloadable brass cases.

    This .300 AAC ammunition from Fiocchi is a great choice for range use. Each cartridge in this box of 50 fires a 150 grain full metal jacket bullet at a supersonic muzzle velocity of 1,925 feet per second. While this velocity creates a sonic "crack" that suppressors commonly used with this caliber cannot eliminate, it also gives the round better extended-range performance.

    Fiocchi ammunition sold in the US is mostly loaded in Ozark, Missouri, with the balance being imported from Lecco, Italy.

    This ammo uses non-corrosive Boxer primers and reloadable brass cases.
