CCI Clean-22 Suppressor 22LR ammunition addresses the single biggest pain point for suppressed rimfire shooters: lead and carbon buildup inside the can. The proprietary Total Synthetic Jacket (TSJ) polymer coating bonds to the 45-grain lead round nose projectile, creating a barrier that reduces fouling deposits by up to 60 percent compared to uncoated lead bullets. At 1000 feet per second muzzle velocity and 100 foot-pounds of energy, this subsonic load stays hearing-safe through any rimfire suppressor while delivering reliable cycling in semi-automatic pistols and rifles. CCI loads each round with non-corrosive primers and temperature-stable propellant for consistent ignition across storage and field conditions.
Performance at a Glance
The TSJ polymer layer accomplishes two tasks: it encapsulates lead vapor at ignition, preventing adhesion to suppressor baffles, and it lubricates the bore during bullet travel, reducing copper and lead streaking in the rifling. The 45-grain weight balances expansion ratio in short barrels while maintaining enough momentum to trip the bolt or slide in blowback actions. Because the load remains subsonic from both pistol and rifle barrels, you eliminate the supersonic crack that negates suppressor effectiveness with high-velocity 22LR loads.

Field testing across Ruger 10/22, Smith & Wesson M&P 15-22, and Browning Buck Mark platforms confirms reliable cycling with both aluminum and steel suppressor baffles. The polymer coating does not increase bore leading in unsuppressed firearms, making this load viable for mixed use.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Follow the four universal rules of firearms safety at all times during loading, firing, and unloading.
- Verify current state and local ammunition laws — some jurisdictions impose additional age verification, purchase limits, or registration requirements.
- This product contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm (Proposition 65). Wash hands after handling.
