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.

    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.

    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.

    Thanks to high-quality propellants and precise bullet engineering, these cartridges perform their best when used in suppressed firearms. Because of subsonic loading, these cartridges eliminate the super-sonic crack that suppressors can not silence. They also have a clean-burning powder that minimizes fouling. Order this package and you’ll have 500 rounds of 220-grain .300 AAC Blackout cartridges.

    Because these bullets are designed for sub-sonic performance, they don’t have the rapid speed of other cartridges. They have a muzzle velocity of 1,000 feet per second but only drop to 920 feet per second after 300 yards. Despite the speed, they still have a muzzle energy of 488 foot pounds, making them incredibly reliable at the target.

    These cartridges are made by Federal Premium Ammunition, a leading ammunition company based out of Minnesota. They have a large selection of products for target shooting, hunting of all varieties, and self defense.

    Hornady's Subsonic 300 AAC Blackout ammo provides excellent terminal performance without the noise and recoil of comparable self-defense rounds. These low-velocity cartridges expand predictably at varying speeds due to the design of the 190 grain Sub-X bullets. Crimped into the mouth of each Boxer-primed brass casing, the Sub-X features a flat polymer Flex-Tip that protects the cavity of the hollow point. On impact, the Flex Tip dissipates as the copper jacket curls back over the soft lead core to create devastating wound paths.

    Shooters with a desire to reload spent casings can reuse the new brass. The brass casings are non-corrosive and filled with clean-igniting powders that help reduce caustic buildup in your barrel.

    Hornady ammunition is American-made and the top choice for many shooters. Order your 200-round bulk case today!
