CCI Sub-Sonic 22LR ammo pairs a 40 grain lead hollow point with a muzzle velocity of 1050 feet per second — below the sound barrier for reduced report without a suppressor. Rimfire ammunition operating at subsonic speeds eliminates the supersonic crack while maintaining expansion characteristics on small game out to typical hunting ranges. At 98 foot-pounds of muzzle energy, this load balances penetration and weight retention for squirrel, rabbit, and pest control where noise reduction matters. CCI engineers the hollow point cavity to mushroom predictably at these lower velocities, delivering stopping power without excessive tissue damage on edible game.
Built for the Box
The 40 grain projectile uses a lead alloy construction with a hollow point nose cavity optimized for subsonic expansion. CCI primes each cartridge with their proprietary priming compound — non-corrosive and known for consistent ignition across temperature ranges. The brass case accepts standard crimps and headspaces reliably in any SAAMI-spec 22 Long Rifle chamber. This ammunition functions in semi-automatic rifles and handguns designed for standard-velocity loads; ultra-light bolt actions may require testing for reliable ejection due to the reduced cycling energy.

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 firearm safety — treat every firearm as loaded, keep your finger off the trigger until ready to fire, never point at anything you are not willing to destroy, and know your target and what lies beyond it.
- This product contains lead, a chemical known to the State of California to cause cancer and reproductive harm under Proposition 65. Wash hands thoroughly after handling ammunition and avoid ingestion or inhalation of lead residue.
- Verify that your firearm is rated for standard-velocity 22 Long Rifle ammunition before use. Some ultra-lightweight bolt-action rifles may require manual cycling with subsonic loads due to reduced recoil energy.
