This guide details how to test subsonic .22lr ammunition in a suppressed semi-automatic rifle, as demonstrated by TheFirearmGuy. It covers establishing a baseline with standard rounds, testing subsonic loads like CCI Quiet-22, and understanding the common issue of manual cycling due to insufficient pressure. The process includes sound comparisons and unsuppressed testing, emphasizing safe firearm handling throughout.

Quick Summary

The CCI Quiet-22 .22lr ammunition is exceptionally quiet due to its subsonic velocity (710 fps) and 40-grain bullet weight. While ideal for noise reduction, it typically requires manual cycling in semi-automatic firearms as it lacks sufficient pressure for automatic function.

Frequently Asked Questions

What makes CCI Quiet-22 ammunition so quiet?

CCI Quiet-22 ammunition is designed to be subsonic, traveling below the speed of sound (around 710 fps), and uses a 40-grain Lead Round Nose bullet. This combination significantly reduces the "crack" sound, making it exceptionally quiet, especially when suppressed.

Will CCI Quiet-22 ammunition cycle my semi-automatic .22lr rifle?

Typically, CCI Quiet-22 ammunition does not have enough pressure to reliably cycle the action of most semi-automatic .22lr firearms. You will likely need to manually cycle the bolt after each shot.

How does CCI Quiet-22 compare to standard .22lr ammunition in terms of noise?

When suppressed, CCI Quiet-22 is dramatically quieter than standard .22lr ammunition like CCI Mini-Mag. Even unsuppressed, the Quiet-22 remains remarkably quiet, highlighting its effectiveness for noise reduction.

What firearm was used to test the CCI Quiet-22 ammunition?

The CCI Quiet-22 ammunition was tested in a suppressed bullpup rifle featuring the High Tower Armory 90/22 Chassis, which is built upon a Ruger 10/22 action.
