This video from Big Daddy Unlimited features an experienced shooter testing the sound suppression effectiveness of the SilencerCo Sparrow suppressor on a .22 race gun. The experiment compares three different .22LR ammunition types: CCI Quiet 22 Segmented (710 fps), Armscor 40 grain (1135 fps), and CCI Mini-Mag (1235 fps). The results highlight how ammunition velocity significantly impacts the perceived sound level, even with a suppressor.

Quick Summary

The SilencerCo Sparrow suppressor is tested with various .22LR ammunitions, demonstrating that CCI Quiet 22 Segmented (710 fps) is the quietest. Even faster rounds like Armscor (1135 fps) and CCI Mini-Mag (1235 fps) are manageable, though the latter is the loudest. This highlights how ammunition velocity significantly impacts sound suppression effectiveness.

Frequently Asked Questions

How quiet is the SilencerCo Sparrow suppressor with .22LR ammunition?

The SilencerCo Sparrow is notably quiet, especially with subsonic .22LR rounds like CCI Quiet 22 Segmented (710 fps). Even faster rounds like Armscor (1135 fps) remain relatively quiet, and supersonic CCI Mini-Mag (1235 fps) is manageable, allowing shooting without hearing protection in some scenarios.

What types of .22LR ammunition were tested with the SilencerCo Sparrow?

The test included CCI Quiet 22 Segmented (710 fps), Armscor 40 grain .22LR (1135 fps), and CCI Mini-Mag .22LR (1235 fps). This range demonstrates the impact of velocity on sound suppression effectiveness.

Can you shoot a suppressed .22LR firearm without hearing protection?

While a suppressor significantly reduces noise, it's not always safe to shoot without hearing protection. Subsonic rounds like CCI Quiet 22 are very quiet. However, supersonic rounds, even when suppressed, can still exceed safe noise levels, making hearing protection advisable for extended shooting.

What factors affect the sound level of a suppressed .22LR firearm?

The primary factor is ammunition velocity. Subsonic rounds (under the speed of sound) are inherently quieter than supersonic rounds. The suppressor's design and the firearm itself also play roles, but ammunition choice is critical for maximizing sound reduction.
