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...

    Grab a few boxes of this affordable .300 AAC Blackout ammunition from Sellier & Bellot for your appropriately chambered AR and enjoy some quality time at the range. While it achieves supersonic velocities and will not take full advantage of the noise dampening potential of a suppressor, this ammo can be used with both suppressed and non-suppressed builds.

    Each cartridge in this box of 20 fires a 124-grain full metal jacket bullet at 2,165 feet per second out of the muzzle. This results in good medium-range performance and flatter trajectories than those possible with subsonic loads.

    Sellier & Bellot is a Czech manufacturer established in the early 1800s to supply what was then the Austrian Empire with ammunition. S&B ammo uses non-corrosive Boxer primers and reloadable brass cases. The company is part of CBC, which also produces Magtech in Brazil and MEN ammo in Germany.

    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.
