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.

    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.

    These rounds have a muzzle velocity of 1,000 feet per second and an energy of 488 foot pounds.

They have excellent stability, consistency, and performance that rivals a standard full metal jacket round.

    Federal Premium Ammunition is a leader in top-quality rounds. Since 1922, this Minnesota-based manufacturer has been making cartridges that are trusted by hunters and target shooters. They not only have some of the best round for a wide range of purposes, they also have supplies and equipment for reloading.

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.

    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.

    Want to deliver the power of the 7.62 but on the AR-15 platform? Fret not, this round is for you! The 300 AAC Blackout packs the punch of a 30 caliber round but is designed for the AR-15. Be careful however, this round does not have as long of an effective range as standard AR-15 rounds and requires special components to shoot. If those limitations don't bother you, this round is your perfect choice!

    Instead of the wimpy 55 or 62 grain 223, slap in a 220 grain subsonic 300 AAC Blackout round. These open tip match rounds are fantastic for range shooting. With great precision and more wind resistance than any other AR-15 rounds, you will have much more accuracy. Pick up 200 rounds and get to blasting!

    If you're pushing your 300 AAC rifle out to longer distances at the range, try this ammunition from Fiocchi's Shooting Dynamics series. This ammo comes at a great price thanks to the 500 round case size.

    Each cartridge in this case propels a 150 grain full metal jacket bullet to a muzzle velocity of 1,925 feet per second. This is a supersonic velocity that will still produce a sonic 'crack' when fired with a suppressor, although the noise caused by the propellant will be dampened. It makes an excellent target shooting load for a rifle sighted in for hunting.

    Fiocchi ammunition is manufactured in the USA and Italy; most Fiocchi cartridges sold here are also made here. This ammo uses reloadable brass casings and non-corrosive Boxer primers.
