As the popularity of the AR platform continues to grow, so too does the demand for a new cartridge that can deliver superior performance. One such example is the .300 Blackout and the 8.6 Blackout. While both of these cartridges have their unique advantages, it's essential to understand the differences between them. In this article, we'll delve into the history, ballistics, and best uses of each cartridge along with major differences so you can make an informed decision when purchasing one, or both.
History
The .300 Blackout, also known as the 7.62×35mm, was created by Advanced Armament Corporation (AAC) in cooperation with Remington Defense. The idea behind this cartridge was to provide military and law enforcement personnel with a more effective round for close quarters combat. This cartridge is designed to fit into standard 5.56mm AR magazines, which makes it easy to use for individuals already familiar with the platform.
On the other hand, the 8.6 Blackout is a relatively new cartridge that was created by Q, the company who gave us the Honey Badger. Unlike the .300 Blackout, which was designed for close-quarters combat, the 8.6 Blackout was created with long-range precision shooting in mind.
Ballistics
When it comes to ballistics, there are a few critical differences between the two cartridges. For starters, the .300 Blackout has a muzzle velocity of 2,215 fps, while the 8.6 Blackout has a muzzle velocity of 2,700 fps. The 8.6 Blackout is designed to be a high-velocity cartridge that's ideal for long-range shooting.
When it comes to accuracy, the 8.6 Blackout has the upper hand, with a higher ballistic coefficient (BC) than the .300 Blackout. The higher BC allows the bullet to travel further and more accurately, making it an excellent choice for long-range shooting.
Best Uses
So, what are the best uses for each of these cartridges? The .300 Blackout is best suited for close-quarters combat and hunting medium-sized game. Due to its short-range capabilities, it's perfect for situations where you need to be agile and maneuverable.
The 8.6 Blackout, on the other hand, is ideal for long-range precision shooting. Its high-velocity capabilities, coupled with its accuracy, make it perfect for shooting competitions and long-range hunting. However, it's not suitable for close-quarters combat due to its long-range capabilities. When compared to the 300 Blackout, the 8.6 Blackout takes long-range shooting to another level. With the accuracy of a traditional hunting rifle, and velocities rivaling some magnum calibers, this cartridge can consistently produce 1000 ft-lbs of energy beyond 1000 yards. At long range, its improved sectional density gives it superior ballistics to the 300 Blackout, making it a viable option for hunting medium-sized game at long ranges.
AR Platform
One significant difference between the .300 Blackout and the 8.6 Blackout is their compatibility with the AR platform. The .300 Blackout is compatible with standard 5.56mm AR magazines, which means that 300 Blackout is totally adaptable to AR-15 platform and individuals who are already familiar with the platform will have no problem using it. It also allows users to switch back and forth between the 5.56 Nato and 300 Blackout cartridges without having to make any significant changes to their firearms.
The 8.6 Blackout utilizes AR-10 platform. Don't be confused by the middle name, 8.6 Blackout is totally a different animal when compared to 300 Blackout.
Differences between 8.6 Blackout and 300 Blackout
1. Size
The most obvious difference between these two calibers is their size. The 8.6 Blackout is a relatively new caliber, and as such, it is significantly larger than the 300 Blackout. Specifically, the 8.6 Blackout cartridge has a case length of 1.75 inches and an overall length of 2.7 inches. The 300 Blackout, on the other hand, has a case length of 1.37 inches and an overall length of 2.26 inches.
2. Bullet Weight
Another difference between these two calibers is the weight of their bullets. The 8.6 Blackout typically fires a bullet that weighs between 180 and 220 grains, whereas the 300 Blackout typically fires a bullet that weighs between 110 and 130 grains.
3. Velocity
Velocity is a crucial factor when it comes to choosing ammunition for your firearm. The 8.6 Blackout has a much higher velocity than the 300 Blackout. Specifically, the 8.6 Blackout typically has a velocity of around 2,700 feet per second, whereas the 300 Blackout typically has a velocity of around 2,100 feet per second.
4. Range
The range of a firearm is another important consideration when choosing ammunition. The 8.6 Blackout has a much longer range than the 300 Blackout. Specifically, the 8.6 Blackout is capable of firing accurately out to around 800 yards, whereas the 300 Blackout is typically only accurate out to around 300 yards.
