Understanding Blackout Ammo: Performance and Reloading Insights
The world of firearms has seen significant advancements in recent years, with one of the most notable developments being the rise of blackout ammo. This type of ammunition has gained popularity among shooters and hunters due to its versatility and performance. In this article, we will delve into the world of blackout ammo, exploring its characteristics, performance, and reloading insights.
What is Blackout Ammo?
Blackout ammo, also known as 300 AAC Blackout (7.62x35mm), is a rifle cartridge designed to be used in AR-15 rifles. It was developed by Advanced Armament Corporation (AAC) in the early 2000s as a response to the need for a.30-caliber cartridge that could be used in standard AR-15 magazines and rifles. Blackout ammo is designed to provide a high level of performance, with a flatter trajectory and increased range compared to traditional 5.56mm ammunition.
Characteristics of Blackout Ammo
Blackout ammo has several key characteristics that make it an attractive option for shooters:
- Bullet weight: Blackout ammo typically uses heavier bullets, ranging from 78 to 220 grains, which provide a more stable flight path and increased range.
- Case length: The case length of blackout ammo is 1.359 inches, which is slightly longer than traditional 5.56mm ammunition.
- Pressure: Blackout ammo operates at a higher pressure than traditional 5.56mm ammunition, with a maximum average pressure of 55,000 psi.
- Muzzle velocity: The muzzle velocity of blackout ammo ranges from 2,000 to 2,400 feet per second, depending on the bullet weight and powder charge.
Performance of Blackout Ammo
Blackout ammo has been extensively tested and evaluated, with the following performance characteristics observed:
- Accuracy: Blackout ammo has been shown to be highly accurate, with some loads achieving sub-MOA accuracy at 100 yards.
- Range: The effective range of blackout ammo is approximately 400-500 yards, depending on the bullet weight and trajectory.
- Penetration: Blackout ammo has been shown to penetrate deeply, with some loads penetrating up to 12 inches in ballistic gelatin.
- Expansion: The expansion of blackout ammo is moderate, with some loads achieving up to 1.5 times the original bullet diameter.
Reloading Blackout Ammo
Reloading blackout ammo can be a bit tricky, but with the right tools and techniques, it can be a rewarding experience. Here are some reloading insights to keep in mind:
- Bullet selection: When reloading blackout ammo, it’s essential to choose the right bullet weight and type. Heavier bullets tend to perform better at longer ranges, while lighter bullets are better suited for closer ranges.
- Powder selection: The choice of powder is critical when reloading blackout ammo. Some popular powders include H110, H115, and Lil’Gun.
- Charge weight: The charge weight of blackout ammo is typically between 18-22 grains, depending on the powder and bullet weight.
- Seating depth: The seating depth of the bullet is critical, as it can affect the overall performance of the cartridge. A seating depth of 0.020-0.030 inches is recommended.
💡 Note: When reloading blackout ammo, it's essential to follow proper safety protocols and use a reliable reloading manual to ensure accuracy and safety.
Converting to Blackout Ammo
Converting to blackout ammo can be a relatively straightforward process, but it requires some specialized tools and knowledge. Here are some steps to follow:
- Barrel conversion: The first step in converting to blackout ammo is to install a new barrel. This can be done by a qualified gunsmith or by purchasing a pre-made barrel.
- Upper receiver conversion: The next step is to convert the upper receiver to accept the new barrel. This may require a new bolt carrier group and charging handle.
- Magazine conversion: The final step is to convert the magazine to accept the new ammunition. This can be done by replacing the magazine follower and spring.
🔧 Note: Converting to blackout ammo can be a complex process, and it's recommended to seek the advice of a qualified gunsmith or firearms expert.
