The 8.6 Blackout compared to .338 Federal is a question many shooters and hunters are asking, and COMPARE.EDU.VN is here to provide a comprehensive comparison. By understanding the nuances of each cartridge, you can make an informed decision that suits your specific needs. We delve into the specifications, performance, and intended applications to help you decide which round is superior.
1. Introduction to 8.6 Blackout and .338 Federal
The .338 Federal and 8.6 Blackout (BLK) represent distinct approaches to achieving enhanced ballistic performance in short-action cartridges. The .338 Federal, commercially backed by Federal Premium and developed with Sako in 2006, is essentially a .308 Winchester necked up to accommodate .338-caliber bullets. This straightforward modification aimed to provide improved hunting capabilities compared to the .308 Win, offering better ballistics through heavier bullet weights and increased frontal surface area. The result is a cartridge that delivers slightly better penetration, more energy, and a larger wound cavity, making it a viable option for hunters seeking an edge.
In contrast, the 8.6 BLK, based on a shortened 6.5 Creedmoor, was engineered by Q, the company behind the Honey Badger, with the goal of achieving unique performance characteristics that the .338 Federal cannot match. The 8.6 BLK is designed to excel in suppressed shooting scenarios and short-barreled rifles. Its shortened case allows for the use of heavy bullets without magazine length limitations, making it ideal for subsonic applications. Additionally, the 8.6 BLK’s fast 1:3” twist rate imparts a very high spin rate on the bullet, which results in dramatic terminal effects upon impact with soft tissue. This combination of features makes the 8.6 BLK a versatile cartridge with a focus on specialized applications.
2. Key Similarities Between .338 Federal and 8.6 Blackout
Despite their differences, the .338 Federal and 8.6 Blackout share a few key similarities:
2.1. Bullet Caliber
Both cartridges utilize .338-diameter bullets. This means that they both launch projectiles of the same width, which can influence factors like penetration and wound channel size.
2.2. Action Type
Both rounds are designed to function in short-action rifles. This allows them to be used in common platforms like bolt-action rifles and AR-10-style semi-automatic rifles.
2.3. Magazine Compatibility
Due to their short-action compatibility, both cartridges can generally use the same magazines, meaning that ammo capacity is roughly equal when comparing rifles chambered in these calibers.
3. Core Differences Between 8.6 Blackout and .338 Federal
3.1. Design and Ballistics
The .338 Federal is a .308 Winchester necked up to .338 caliber, pushing a 200-grain bullet to around 2,700 fps. It offers improved ballistics over the .308 Win, with better penetration and energy due to its heavier bullet and larger frontal surface area.
Necking down a 6.5 Creedmoor case illustrates the process behind cartridges like the .338 Federal, where a parent case is modified to accept a larger caliber bullet, enhancing ballistic performance.
The 8.6 BLK, based on a shortened 6.5 Creedmoor, is designed for unique performance, particularly in suppressed shooting. Its shorter case allows for heavy bullets and efficient powder combustion in short barrels.
3.2. Suppressor Compatibility
The 8.6 BLK is specifically designed for suppressed shooting, excelling in subsonic applications due to its case design and heavy bullet options.
The .338 Federal, while it can be used with a suppressor, does not offer the same level of sound mitigation because it typically fires supersonic projectiles.
3.3. Barrel Length and Powder Efficiency
The 8.6 BLK is ideal for short-barreled rifles, achieving full powder combustion in these platforms without significant velocity loss. This makes it more maneuverable in hunting blinds and stands.
The .338 Federal benefits from longer barrels to maximize its velocity and energy, making it less optimized for very short barrels.
3.4. Twist Rate and Terminal Ballistics
The 8.6 BLK utilizes a very fast 1:3” twist rate, imparting a high spin rate on the bullet. This results in significant rotational energy and increased tissue disruption upon impact, creating a more detrimental wound cavity.
The .338 Federal uses a standard twist rate, which does not provide the same level of rotational force and terminal effects as the 8.6 BLK.
3.5. Ammunition Options
While both cartridges have fewer ammo options compared to more common rounds like .308 or 5.56, the 8.6 BLK is showing promise with specialized loads designed for various barrel lengths and suppressor use.
The .338 Federal has limited factory loads, typically featuring 200-grain bullets, and its handloading data often falls short of the factory load performance.
4. Detailed Performance Analysis
4.1. Velocity and Energy Comparison
| Cartridge | Bullet Weight (grains) | Velocity (fps) | Energy (ft-lbs) |
|---|---|---|---|
| .338 Federal | 200 | 2,700 | 3,237 |
| 8.6 Blackout | 210 | 2,000 | 1,865 |
| 8.6 Blackout Sub | 342 | 1,000 | 761 |
As shown, the .338 Federal offers higher velocity and energy with its standard loads compared to the supersonic 8.6 Blackout, while the subsonic 8.6 Blackout sacrifices energy for suppressed performance.
4.2. Terminal Ballistics
The 8.6 BLK’s fast twist rate leads to enhanced terminal effects, causing bullets to expand and lacerate tissue more effectively.
Gorilla Ammunition offers specialized loads for the 8.6 Blackout, designed to optimize terminal ballistics and performance in various barrel lengths, enhancing its appeal for hunters and tactical shooters.
