Understanding the Cartridges: .300 BLK OT and .223 Remington

.300 Blackout (BLK) – Optimized for Subsonic

The .300 BLK was developed to offer .30 caliber performance in the AR-15 platform while maintaining compatibility with standard AR magazines and bolt carriers. Its primary design goal was to provide a cartridge effective in suppressed rifles and short-barreled rifles (SBRs). The “OT” designation often refers to optimized subsonic loads, which are specifically designed for quiet operation and enhanced terminal ballistics at lower velocities. These loads typically utilize heavier bullets to retain energy at subsonic speeds. While the .300 BLK shines in close-quarters combat (CQB) and suppressed applications, its long-range performance is often debated.

.223 Remington / 5.56 NATO

The .223 Remington (also known as 5.56 NATO when loaded to military specifications) is a high-velocity, lightweight cartridge known for its flat trajectory and accuracy at moderate ranges. It has been a staple of the AR-15 platform since its inception and is widely available in various bullet weights and configurations. The .223’s effectiveness at longer ranges is well-documented, making it a popular choice for target shooting, varmint hunting, and even some tactical applications. However, its performance can be affected by factors such as wind drift and bullet drop, especially at extreme distances.

Ballistics: A Critical Comparison for Long Range

Velocity and Energy Retention

One of the most significant differences between the .300 BLK OT and the .223 is their velocity. The .223 is a high-velocity cartridge, typically achieving velocities of 3000+ fps with lighter bullets. This high velocity translates to a flatter trajectory and better energy retention at longer ranges. The .300 BLK OT, on the other hand, is designed for subsonic velocities, typically around 1000-1100 fps. This lower velocity results in a significantly more curved trajectory and a rapid loss of energy at longer ranges.

Trajectory and Bullet Drop

Due to its higher velocity, the .223 exhibits a much flatter trajectory than the .300 BLK OT. This means that the .223 bullet will drop less over a given distance, making it easier to hit targets at varying ranges. The .300 BLK OT, with its lower velocity, experiences a significant amount of bullet drop, requiring more precise range estimation and holdover adjustments, especially at distances beyond 100 yards. In our experience, accurately judging distance is paramount when using subsonic .300 BLK at longer ranges.

Wind Drift

Wind drift is another critical factor to consider when shooting at long ranges. The .223, with its higher velocity and typically lighter bullets, is more susceptible to wind drift than the .300 BLK OT, which generally uses heavier bullets. However, the .300 BLK OT’s lower velocity means the bullet spends more time in the air, potentially negating some of the advantages of the heavier bullet. The effects of wind drift are complex and depend on various factors, including bullet shape, ballistic coefficient, and wind speed.

Ballistic Coefficient (BC)

The ballistic coefficient (BC) is a measure of a bullet’s ability to overcome air resistance. A higher BC indicates a more aerodynamic bullet that will retain its velocity and resist wind drift better. While some .300 BLK bullets have relatively high BCs, the lower velocity of the cartridge ultimately limits its long-range performance compared to the .223, which can utilize bullets with excellent BCs at much higher velocities. The BC is essential to determine trajectory and bullet drop.

Practical Applications: Where Each Cartridge Excels

.223 Remington: A Versatile Long-Range Option

The .223 Remington is a versatile cartridge that excels in various long-range applications. Its flat trajectory and good energy retention make it suitable for target shooting, varmint hunting, and even some tactical scenarios. The .223’s widespread availability and relatively low cost also make it an attractive option for high-volume shooting and training.

.300 BLK OT: Specialized Role in CQB and Suppressed Fire

The .300 BLK OT, while not ideally suited for long-range shooting, has a specialized role in close-quarters combat (CQB) and suppressed fire. Its subsonic velocity and heavier bullets make it exceptionally quiet when used with a suppressor, and its improved terminal ballistics at close range can be advantageous in certain situations. However, its limitations at longer ranges must be carefully considered.

The Role of Optics and Accessories

Optics for .223 Long Range

When shooting the .223 at long range, a quality optic is essential. A variable power scope with a ballistic reticle or turrets calibrated for bullet drop compensation (BDC) can significantly improve accuracy. A rangefinder is also a valuable tool for accurately determining the distance to the target.

Optics for .300 BLK OT Long Range (If Attempted)

If attempting to use the .300 BLK OT at longer ranges, a specialized optic with a reticle calibrated for subsonic trajectories is highly recommended. Alternatively, a scope with adjustable turrets can be used, but precise range estimation and holdover adjustments are crucial. Given the significant bullet drop, a rangefinder is virtually essential.

Ammunition Selection: Maximizing Performance

.223 Ammunition for Long Range

For long-range shooting with the .223, heavier bullets with high ballistic coefficients are generally preferred. Bullet weights in the 69-77 grain range are popular choices, as they offer a good balance of velocity and wind resistance. Match-grade ammunition is also recommended for optimal accuracy.

.300 BLK OT Ammunition for Long Range (Compromises)

If attempting long-range shooting with the .300 BLK OT, selecting the right ammunition is critical. Look for heavier bullets with the highest possible ballistic coefficient. However, remember that even with the best ammunition, the .300 BLK OT will still be significantly limited compared to the .223 at longer ranges.
