Quietest Subsonic .22 LR Ammo: Best Loads for Suppressors, Accuracy, and Small Game

.22 Long Rifle ammunition is one of the most affordable and enjoyable cartridges to shoot, and subsonic loads make it even better.

When paired with a suppressor, the right subsonic .22 LR ammo can dramatically reduce noise while maintaining excellent accuracy and dependable performance. For plinking, pest control, and small game hunting, it is difficult to beat a quality suppressed rimfire setup.

This guide covers the quietest subsonic .22 LR loads, how they perform, and what to consider before buying.

What Is Subsonic .22 LR Ammo?

Subsonic .22 Long Rifle ammunition is loaded so the bullet stays below the speed of sound.

v<1125fps

v < 1125\ \text{fps}

v<1125 fps

Most subsonic .22 LR loads push a 38- to 45-grain bullet at approximately 950 to 1,080 fps.

Because the projectile does not break the sound barrier, these loads eliminate the sonic crack and produce a significantly quieter report when suppressed.

Why Use Subsonic .22 LR Ammo?

Shooters choose subsonic .22 LR for several reasons:

• Extremely low noise with a suppressor
• Excellent accuracy in many rifles
• Reduced disturbance for backyard pest control where lawful
• Minimal recoil
• Affordable cost per round

For many suppressor owners, subsonic .22 LR offers the best cost-to-enjoyment ratio of any cartridge.
