Can You Shoot Subsonic Unsuppressed? Yes, but...
The short answer is yes, you can shoot subsonic ammunition unsuppressed. However, the "but..." is crucial. While technically feasible, shooting subsonic ammunition without a suppressor offers several significant drawbacks compared to suppressed shooting. Let's explore the nuances:
What is Subsonic Ammunition?
Subsonic ammunition is designed to travel slower than the speed of sound (approximately 1125 feet per second or 343 meters per second). This slower velocity reduces the characteristic "crack" of a supersonic bullet breaking the sound barrier, leading to a quieter shot. However, even subsonic rounds produce noise.
Why Suppressors Are Recommended for Subsonic Ammo
While subsonic rounds are inherently quieter than supersonic rounds, firing them unsuppressed still generates considerable noise. This noise comes from several sources:
-
The mechanism of the firearm: The action of the firearm itself – the slide cycling, the hammer striking the firing pin, and the ejection of the casing – creates significant sound. This noise is often louder than the report of the bullet, especially with subsonic ammunition.
-
The bullet's impact: The impact of the bullet on the target contributes to the overall sound. While less than a supersonic round, it's still significant.
-
Muzzle blast: Even though the bullet is traveling subsonically, there is still a measurable amount of expanding gas escaping the muzzle which creates noise.
Why Use Subsonic Ammo at All?
Subsonic ammunition finds its place in specific scenarios:
-
Stealth: In situations demanding quiet operation, such as hunting or law enforcement, subsonic ammunition is essential for minimizing noise. Even though a suppressor isn't used, subsonic rounds offer a significant reduction in sound compared to their supersonic counterparts.
-
Reduced recoil: Subsonic rounds often have slightly less recoil compared to their supersonic equivalents due to their lower velocity.
-
Specific firearm limitations: Some firearms might struggle with certain types of supersonic ammunition, but perform better with the lower pressures of subsonic loads.
Are There Disadvantages to Using Subsonic Ammo Unsuppressed?
Yes, the primary disadvantage is the significant noise reduction missed by not using a suppressor. You're not achieving the full potential of the subsonic ammunition. The effectiveness of the subsonic round in terms of stealth is severely compromised.
How Much Quieter is Subsonic Unsuppressed Compared to Supersonic?
While significantly quieter than supersonic ammunition, unsuppressed subsonic rounds are still considerably louder than suppressed subsonic rounds. The difference can be substantial, impacting both the shooter's hearing and situational awareness.
What is the Best Ammunition for Unsuppressed Subsonic Shooting?
The "best" ammunition depends on the specific firearm and intended purpose. Heavier bullets generally perform better in subsonic applications, offering better accuracy and energy transfer at longer ranges. The type of powder used significantly affects both noise and performance.
In conclusion, while feasible, shooting subsonic ammunition unsuppressed is generally less effective than using a suppressor. A suppressor dramatically reduces the noise generated by both the projectile and the firearm mechanism, maximizing the benefits of the subsonic round in terms of sound reduction and stealth. The choice to shoot subsonic ammunition unsuppressed should be made consciously, understanding the limitations and potential drawbacks.
