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.

    The beauty of Russian steel! Wolf’s ammunition features plenty of ferrous metal that will keep your wallet fatter. It’s going to attract a magnet, sure, but it’s going to save you money as well!

    This cartridge is loaded with a 145 grain bullet, which gives a 300 Blackout rifle that supersonic muzzle velocity which simplifies long-distance shooting. The bullet’s copper-washed exterior is only skin deep – beneath it lies a hard, deformation resistant layer of soft steel.

    Wolf’s steel cases aren’t outright impossible to reload. With special equipment and enough time you’ll be able to do it. But is it worth it? No – unless there was absolutely no other way to get 300 Blackout ammo. But while they are effectively non-reloadable, Wolf’s cases do wear PolyFormance polymer coating to protect them from corrosion and smooth out cycling in a semi-auto.

    This ammo’s Berdan primers operate on a slightly different principle than America’s preferred Boxer primer – but they are just as non-corrosive!

    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.

    The 5.56x45 is so last week. All the coolest, handsomest shooters are into 300 AAC Blackout now. This is your chance to be one of them, because we have Winchester USA 300 Blackout in stock and ready to ship to your base of operations!

    This is a target shooting cartridge, but it has a little more going for it than the standard FMJ load. Its open tip bullet is enhanced to deliver a flat and accurate trajectory thanks largely to its form-fitted lead core. Alongside its perfectly flat base, precision jacket and narrow nose cavity, this round’s 125 grain open tip is able to achieve a ballistic coefficient of 0.272. It’ll stay supersonic until about 470 yards – a range it reaches in 0.92 seconds!

    Please note that the open tip bullet is built exclusively for accuracy. That nose cavity is only there because it gave passage to the molten lead that would form the open tip’s core. It will not unleash terminal expansion inside a quarry or threat.

    This nonmagnetic and non-corrosive ammo is loaded in Illinois with freshly minted brass cases. The cases are gray around their shoulders because they were heat treated without subsequently getting polished up for better cosmetics.

    Although it hasn't been around for too long, the 300 AAC Blackout has quickly become a popular round among shooters who are tired of the measly performance of the typical AR-15 rounds, the 223 Rem and 5.56mm. With this new round, you have increased range, more energy, and better ballistics, making it fantastic hunting, self defense, match shooting, and plinking around with only a few modifications to the rifle.

    Federal has been making some of the best ammunition in America since their beginnings in the 1920's and continue to make some of America's favorite ammunition due to their amazing manufacturing and often highly affordable prices. With these Federal American Eagle, 150 grain, full metal jacket, boxer primed, brass cased rounds, you get all the accuracy and reliability you need to have a blast practicing at the range. Firing at 1900 feet per second, these range rounds come at a great price, helping you save money while you get better at shooting.

    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.
