CCI Suppressor Max .22 LR ammunition (part no. CCIA22SMX) loads a 45-grain segmenting hollow point at a subsonic 970 feet per second, built specifically for shooters running rimfire suppressors. CCI engineered the load to stay under the sound barrier so it never produces the crack of a supersonic round, while still cycling reliably in semi-automatic rifles and pistols. The hollow point segments on impact even at that reduced velocity, unlike conventional rimfire loads that rely on speed to open up. Whether you’re running a suppressed 10/22 or a suppressed rimfire pistol, this is the round built to keep both performance and noise reduction intact.

Key Specifications

• Chambered in .22 LR, the standard rimfire cartridge for suppressed plinking and pest control.
• The bullet weighs 45 grains, CCI’s proven weight for reliable rimfire hollow points.
• It’s a segmenting hollow point, built to fragment on impact instead of relying on velocity alone.
• Segmentation happens reliably even at subsonic speed, which conventional rimfire hollow points can’t manage.
• Muzzle velocity runs 970 feet per second, staying below the sound barrier for quiet suppressed shooting.
• The load is rated safe through any rimfire suppressor, not just one manufacturer’s can.
• It’s built to cycle semi-automatic rimfire actions at subsonic speed, where many quiet loads short-stroke.
• Cases are brass, standard rimfire construction for reliable extraction.
• Each box holds 100 rounds, enough for a long suppressed range session.
• Per-round cost runs about $0.14, affordable enough for high-volume suppressed practice.

Frequently Asked Questions

Will this ammo cycle a suppressed semi-auto? Yes, Suppressor Max is loaded specifically to cycle semi-automatic rimfire rifles and pistols at its subsonic 970 fps velocity, not just work in bolt actions.

Is this round safe to shoot through any suppressor? Yes, CCI rates the segmenting hollow point safe through all rimfire suppressors, not a specific proprietary can.

Why does the bullet still expand at subsonic velocity? CCI’s segmenting hollow point is engineered to fragment on impact rather than rely on speed, so it performs the same whether it’s loaded hot or subsonic.

Buy CCI Suppressor Max .22 LR 45gr Subsonic

Suppressed rimfire shooting only works if the ammunition actually stays quiet and still cycles the action, and Suppressor Max is built to do both. Load a box before your next suppressed range trip and feel the difference a purpose-built subsonic load makes over standard-velocity ammo.
