What is .300 Blackout?

The .300 AAC Blackout (also known as 300 BLK or 300 Blackout) was originally developed to give AR-15 users more power and flexibility without changing their rifle platform. With simple barrel swaps, shooters can transition from 5.56 NATO to .300 Blackout, enjoying heavier bullets and excellent subsonic performance.

The round offers incredible versatility. It can be loaded for quiet, suppressed shooting or high-velocity performance. That’s why the .300 Blackout has become a favorite among hunters, tactical shooters, and enthusiasts who demand control and precision in any scenario.

Why Choose Steinel .300 Blackout Ammo?

At Steinel Ammo, we manufacture our 300 Blackout rounds with exacting precision and American-made quality. Every cartridge is built for dependable performance from the clean-burning powder to the carefully inspected brass.
Here’s what sets our .300 Blackout ammo apart:

1. Reliable Subsonic & Supersonic Options

Whether you prefer the quiet precision of 200gr 300 Blackout subsonic ammo or the speed of supersonic rounds, Steinel delivers the perfect balance. Our subsonic rounds pair beautifully with suppressors, minimizing noise without sacrificing accuracy.

2. Consistent Ballistics

Every Steinel .300 Blackout round is engineered for tight velocity tolerances and stable trajectories. That means predictable performance from shot to shot, whether you’re target shooting or hunting.

3. Clean-Burning Components

We use clean-burning propellants that reduce carbon buildup in your firearm. Less fouling means smoother cycling and easier maintenance after your range session.

Choosing the Right .300 Blackout Ammo

The beauty of 300 Blackout ammunition lies in its flexibility. You can tailor your setup based on your shooting style and purpose.
Here’s how to pick the right Blackout shells for your needs:

For Suppressed Shooting

If you’re using a suppressor, go with 200gr 300 Blackout subsonic ammo or heavier rounds. These travel below the speed of sound, reducing noise and improving stealth. Perfect for tactical training or pest control where sound matters.

For Hunting

Hunters often choose supersonic 300 Blackout rounds for their high velocity and hard-hitting power. The heavier bullet weight gives excellent energy transfer and controlled expansion, making it ideal for deer and hog hunting within 200 yards.

For Target Practice

Looking to put rounds downrange and improve accuracy? Our .300 Blackout ammo offers smooth feeding and reliable performance, ensuring consistent results shot after shot.

For Home Defense

The .300 Blackout provides superior stopping power compared to smaller calibers. Combined with Steinel’s premium construction, it’s an excellent choice for personal defense when reliability matters most.

The Advantages of .300 Blackout Over Other Calibers

Many shooters wonder how the 300 Blackout compares to traditional rounds like the 5.56 NATO. Here’s why more and more shooters are making the switch:

  • Heavier Bullet Weights – The .300 BLK can handle bullets from 110gr to 220gr, giving shooters more flexibility.
  • Better Suppressed Performance – Subsonic 300 Blackout rounds are quieter and smoother than most other calibers when paired with suppressors.
  • Short-Barrel Efficiency – Designed for short barrels, it delivers impressive energy even from compact rifles and pistols.
  • Easy Conversion – You can use your existing AR-15 platform; only the barrel needs to be changed.

Safety, Storage & Shooting Tips

To get the best performance and longevity from your .300 Blackout ammo, follow these best practices:

  • Store in a cool, dry place to prevent moisture exposure.
  • Always verify your firearm is chambered for .300 Blackout, not 5.56 NATO.
  • Keep ammunition in its original packaging to preserve lot tracking.
  • Clean your firearm regularly to maintain accuracy and reliability.
