.300 Blackout vs .223: A Detailed Ballistic Comparison

When comparing .300 Blackout vs .223, ballistic performance is a crucial factor. The .223 generally exhibits a flatter trajectory and higher velocity at longer ranges, while the .300 Blackout delivers more energy on target, especially at shorter distances.

Velocity and Trajectory

The .223 typically has a higher muzzle velocity than the .300 Blackout. This results in a flatter trajectory, meaning the bullet drops less over distance. This makes the .223 easier to shoot accurately at longer ranges, as less holdover is required. For example, a typical 55-grain .223 round might travel at 3,200 fps, while a 125-grain .300 Blackout supersonic round might travel at 2,200 fps. This difference in velocity is significant.

Energy and Stopping Power

The .300 Blackout, particularly with heavier bullets, delivers more energy on target. This translates to greater stopping power, making it a more effective choice for hunting larger game or for defensive purposes where immediate incapacitation is desired. Subsonic .300 Blackout rounds, while slower, still deliver significant energy due to their heavier bullet weights. A 220-grain .300 Blackout subsonic round, for instance, delivers significant energy at close range, even at a lower velocity.

Effective Range

The effective range of both cartridges depends on various factors, including bullet weight, barrel length, and environmental conditions. Generally, the .223 is considered effective out to 500-600 yards, while the .300 Blackout is more effective within 200-300 yards. Beyond these ranges, the .223’s flatter trajectory gives it a distinct advantage. Our testing has shown a noticeable drop in accuracy and energy for the .300 Blackout beyond 300 yards.

Subsonic vs Supersonic: Understanding the Ammunition Options

Both .300 Blackout and .223 ammunition come in various configurations, but the .300 Blackout uniquely offers both subsonic and supersonic options.

Subsonic .300 Blackout

Subsonic .300 Blackout ammunition travels at speeds below the speed of sound (approximately 1,125 feet per second). This makes it ideal for use with suppressors, as it eliminates the sonic boom associated with supersonic rounds. Subsonic .300 Blackout rounds are typically heavier, ranging from 200 to 240 grains, and deliver significant energy at close range.

Supersonic .300 Blackout

Supersonic .300 Blackout ammunition travels at speeds above the speed of sound. These rounds offer a flatter trajectory and greater range than subsonic rounds but are not as effective when used with a suppressor. Supersonic .300 Blackout rounds are typically lighter, ranging from 110 to 150 grains.

.223 Ammunition

.223 Ammunition is almost exclusively supersonic. Bullet weights typically range from 40 to 77 grains. The lighter bullets offer higher velocity and flatter trajectories, while the heavier bullets provide better ballistic coefficients and improved performance in windy conditions.
