300 Blackout Vs. 8.6 Blackout - Don't be fooled by the name

Posted by on June 24, 2023 . 0 Comments.

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.

The 300 Blackout, on the other hand, has a case length of 1.37 inches and an overall length of 2.26 inches.

3. Velocity
