For plinking sessions where noise matters — backyard ranges with close neighbors, rimfire practice in suburban settings, or training new shooters without hearing fatigue — the CCI Quiet Semi-Auto 22LR delivers subsonic performance engineered to cycle semi-automatic actions. At 835 fps, the 45-grain round nose bullet stays below the sound barrier, eliminating the sharp crack of supersonic flight. Unlike earlier quiet loads that stalled in autoloaders, this cartridge generates enough impulse to cycle blowback rifles and pistols with 16- to 24-inch barrels, giving you suppressor-level sound reduction without the tax stamp or the wait. CCI loads this ammunition in the United States, applying decades of rimfire manufacturing experience to a niche that balances decibel reduction with mechanical function.
Performance at a Glance
The 45-grain projectile exits the muzzle at 835 fps, producing 70 foot-pounds of energy — enough to strike steel at 25 yards and punch paper at 50, but well below the impulse of high-velocity loads. Round nose profile promotes reliable feeding in tubular magazines and autoloader chambers. The subsonic velocity reduces perceived report by roughly 30 decibels compared to standard 22LR, making this load hearing-safe for short outdoor sessions (though hearing protection remains recommended for extended shooting). Velocity and energy figures are optimized for barrels 16 to 24 inches; shorter barrels may see velocity drop below the threshold needed for reliable cycling in some semi-autos.

This load is engineered for semi-automatic firearms with barrel lengths from 16 to 24 inches — the range where gas or blowback systems generate enough rearward impulse to extract, eject, and chamber the next round. Bolt-action rifles and single-shots will fire it without issue at any barrel length.
