![]() ![]() It stayed this way when 300 Blackout first rolled out, but grew to include the Remington 700 rifle, Harrington Richardson’s Handi-Rifle, Ruger’s Mini-14, Steyr AUG and numerous other semiautomatics, single shot and bolt action rifles and pistols.īoth versions of 300 Blackout, supersonic and subsonic, have gained popularity with hunters and sportsman on medium to large game such as white-tailed deer, black bear, feral fogs and coyotes. When it was known as 300 Whisper, the cartridge was mostly chambered in AR-15 rifles and Thompson Center Contender single shot rifles and pistols. Most significant was its impact in the realm of suppressed shooting. Fans of the 7.63X39 cartridge gained an equivalency in the AR platform without having to reinvest in magazines for another platform. The 300 Blackout cartridge has made huge inroads into the shooting world since its inception. It should be noted that 300 Blackout and 300 Whisper are fully interchangeable with regard to barrels, rifles, pistols, loading dies, loading components and loading specifications. The only actual part change for a conversion would be replacing the barrel. These changes actually made the round more versatile by allowing the 300 Blackout to fit and function in standard AR-15 magazines intended for 5.56 and to utilize the rifle’s standard bolt carrier group. They submitted the new cartridge specs to SAAMI (Small Arms Ammunition Manufacturers Institute) and CIP (Permanent International Commission for the Proof of Small Arms) for standardization and called this new round 300 AAC Blackout by CIP and 300 BLK by SAAMI. ![]() Around that time an up-and-coming suppressor company known as Advanced Armament Corporation (AAC) took an interest in this round.ĪAC was soon bought by Remington Arms and they worked hand in glove with Remington to produce a new round to address perceived pitfalls regarding the US Military’s 5.56 NATO round.ĭesigners and engineers at both AAC and Remington Defense altered the dimensions of the 300 Whisper by trimming and re-necking 5.56 NATO brass as the parent case instead of 221 Fireball or 222 Remington. The 1994 Federal Assault Weapon Ban had a major impact on this cartridge and its use in semiautomatic rifles because there were limitations on threaded barrels and muzzle devices to one degree or another.įortunately, this misguided piece of legislation came to an end when the sunset clause of the law took effect in January 2004. SSK trademarked the cartridge and kept it proprietary limiting other manufacturers in what they could produce such as reloading dies, reloading components, barrels or firearms. Jones designed this cartridge with two loads in mind: a lighter bullet being used for supersonic rounds comparable to the energy and ballistics of the Russian 7.62 x 39 or 30-30 Winchester round as well as a subsonic load involving heavier projectiles for use in conjunction with a silencer. SSK formed the cartridge case from 221 Fireball brass and expanded the neck size to load a. However, the advantage of 300BLK is that it can easily fit into standard AR-15 magazines while retaining their normal capacity.The 300 Blackout cartridge has a history going back to the 300 Whisper round, developed by JD Jones of SSK Industries between the late 1980s and the early 1990s. The first caliber to launch under this new line is 300BLK, also known as 300 AAC Blackout or 7.62x35mm.įor those not familiar, 300BLK is a cartridge designed for use with AR-15 platform rifles, and it achieves similar ballistics to the Soviet 7.62x39mm commonly used in the iconic AK-47. This First Choice ammo is designed under the same rigorous standards of quality Daniel Defense applies to their weapons, so you know it can depend on it. With this in mind, Daniel Defense has released new line of ammunition known as First Choice. Just like you wouldn't try to run a Formula 1 race car on crude oil, you shouldn't cheap out when it comes to loading your firearm- especially when those very bullets are putting food on your table, or are the only thing between you and an armed criminal. Even if you're not a firearms expert, it's easy to recognize that a quality gun is nothing without quality ammunition. ![]()
