When it comes to selecting the ideal cartridge for your AR-15, two popular options often come to mind: .300 Blackout and 5.56 NATO. Each has its unique advantages, making the choice dependent on your specific needs and shooting scenarios. This guide will help you understand the differences between these two cartridges to make an informed decision.



5.56 NATO: Features and Benefits

5.56 NATO is a lightweight, high-velocity cartridge widely used in military and civilian applications. It's known for its flat trajectory and effectiveness at longer ranges.

Key Features:

  • Velocity: Approximately 3,200 feet per second (fps) with a 55-grain bullet



  • Effective Range: Up to 500 yards



  • Recoil: Low, allowing for quick follow-up shots



  • Cost: Generally more affordable and widely available

The 5.56 NATO is ideal for target shooting, varmint hunting, and situations requiring accuracy at extended distances.



.300 Blackout: Features and Benefits

.300 Blackout was developed to provide superior performance in short-barreled rifles and to function efficiently with suppressors. It offers greater stopping power at close ranges.

Key Features:

  • Bullet Weight: Typically ranges from 110 to 220 grains



  • Velocity:



    • Supersonic: Around 2,200–2,400 fps



    • Subsonic: Approximately 950–1,050 fps



  • Effective Range: Up to 300 yards



  • Recoil: Moderate, with more energy delivered on target

The .300 Blackout excels in close-quarters scenarios, suppressed shooting, and hunting medium-sized game.

Choosing the Right Cartridge

Your choice between 300 Blackout ammo and 5.56 NATO should align with your intended use:

Opt for 5.56 NATO if:

  • You prioritize long-range accuracy



  • Budget and ammo availability are concerns



  • You prefer lower recoil for rapid follow-up shots

Choose .300 Blackout if:

  • You require superior performance in short-barreled or suppressed rifles



  • Close-range stopping power is essential



  • You're hunting medium-sized game or need effective home defense

Safety Considerations

It's crucial to note that while both cartridges can fit in standard AR-15 magazines, they are not interchangeable. Firing a .300 Blackout round in a 5.56 NATO chamber (or vice versa) can be dangerous. Always ensure your firearm is chambered for the correct cartridge.
