Products Overview on 300 BLACKOUT AMMO:
Get 300 Blackout ammo from top ammo manufacturers such as Federal, Remington, Winchester, Hornady, PMC, and others. Whether you are buying bulk 300 Blackout, The superior ballistic performance and cutting-edge technology, 300 blackout ammo is the go-to choice for seasoned shooters and marksmen. This centerfire ammunition, which is also known as 300 blackout ammo, is renowned mostly for its exceptional performance as well as its adaptability. The 300 blackout subsonic ammo round is known to be one of the most adaptable loads available on the market. This is mostly down to the amazing accuracy that it possesses. imageThe solution to the problem of bulky and awkward cartridges is the low-recoiling, high-performance ammunition known as 300 blackout, which is
ideal for target shooting, hunting, and tactical uses. In addition to that, for those who prefer suppressed firing, there is also the 300 blackout subsonic ammo. When compared to other types of rifle ammunition, the 300 Blackout is similar to a hybrid of common military rounds such as the 5.56mm and the 7.62mm.
While the 5.5645mm NATO round has gained widespread acceptance in military circles, the nature of the missions faced by some special operations groups frequently necessitate a round with better performance than high-energy, standard velocity rounds, and subsonic performance greater than the standard 919mm Parabellum (the ubiquitous pistol and submachine gun) round.
To address this demand, AAC collaborated with Remington Defense to develop the 300 blackout ammo The new cartridge was designed to address several of the reported shortcomings of other large caliber cartridges used in the M4. Colt Firearms and other arms manufacturers had previously chambered AR-pattern rifles and carbines in various.30 caliber rounds but ran into issues.
The 7.6239mm’s relatively severe case angle produced feeding challenges unless specially modified AK-47 magazines were used, and even then results were unsatisfactory. Modified bolts were also required due to its higher case head diameter. Similar parts-interchangeability concerns plagued rounds like the 6.8 SPC and 6.5 Grendel, but they did allow for the use of the regular M4/M16 30-round magazine, albeit with a reduced capacity.
Wildcat cartridges like the.300 Whisper series addressed these issues, but their widespread use in single-shot handguns and the lack of an industry standard cartridge dimension meant that many popular loads on both the supersonic and subsonic ends of the spectrum were less than ideal in AR pattern weapons.
Many of these rounds required an excessively long overall cartridge length, preventing feeding in a STANAG magazine while using powder charges that were incompatible with the M4 carbine’s pressure requirements. This was most obvious when employing subsonic ammo with a suppressor, since short stroking and severe fouling would develop, similar to what was seen in the early M16 models in Vietnam.
By keeping the M4 and M16 as primary hosts in mind during load development, designers were able to create a slew of cartridges that not only met the ballistic requirements, but also ensured mechanical reliability with the fewest changes to the weapon itself—with only a simple barrel change required for complete conversion.
“We started development in 2009, but most of the work was done in 2010. A military customer wanted a way to shoot.30-cal. bullets from an M4 platform while using normal bolts and magazines, and without losing the full 30-round capacity of standard magazines. They also wanted a source for ammunition made to their specs. We couldn’t just use.300-221 or.300 Whisper because Remington is a Remington company.”
what ammo does a 300 blackout use
The very advantage of the aac blackout ammo 300 (its similarity to the popular .223/5.56 caliber) can also be a safety issue if ammunition of the two calibers is mixed. Because of similar chamber dimensions between the two calibers, SAAMI has listed the combination of using a 300 BLK round in a .223 chamber as unsafe. Since the bullet of the 300 blackout ammo for sale is larger than the bore of the .223 caliber, chambering and firing causes excessive pressure to build up since the bullet has nowhere to go, which can cause the rifle to explode resulting in risk of injury or death.
Since the mix up can easily be done, some suggest owners of firearms in both calibers carefully separate firearm and ammunition of the two types by, for instance, clearly marking the firearms and magazines, and visually inspect every round while loading magazines. Whether a ammo 300 aac blackout cartridge actually is able to chamber in a .223 barrel depends on bullet length and shape, bullet seating depth, crimping, and the volume of powder charge. Ideally, cartridges would use one of the longer projectiles, a case-filling powder charge, and have the projectile crimped into place.
Hornady 300 Blackout Subsonic Ammunition is designed for accuracy and performance below the speed of sound. The 190 grain Sub-X (Subsonic – eXpanding) bullet features a lead core. Long grooves in its gilding metal jacket combine with the bullet’s flat profile and the patented Flex Tip insert within its hollow-point cavity to help it expand reliably at low velocities. Performance of the 300 Blackout Subsonic load meets or exceeds FBI Protocol terminal ballistic test requirements.
• Impact velocities of 960 to 1,020 fps into ballistic gelatin, providing 16-18” penetration and 90%+ weight retention.
• Designed to expand at velocities down to 900 fps.
• Loaded with unique powders optimized for subsonic use, the low flash signature is ideal for both suppressed and unsuppressed performance.
• Bullets feature a cannelure for a positive case crimp for use in semi-autos.
• Designed specifically to fit, feed, and function in a variety of firearms including gas system guns.

Both rounds were made to be used in an easily converted AR-15. The 6.8 SPC has a more difficult conversion because it was designed around the obsolete .30 Remington cartridge, requiring a different bolt and decreasing standard magazine capacity. The ammunition 300 aac blackout ammo was made specifically for ease of conversion, so the standard bolt will work and a magazine can be used to its full capacity, so the only change needed is the barrel and gas system.
