CCI Subsonic .22 LR 40-grain Lead Round Nose ammunition (brand part no. 934CC) is built for shooters who want quiet, reliable rimfire performance without the sonic crack of standard-velocity loads. CCI Ammunition loads this round with a polymer-coated bullet that cuts copper and lead fouling in the bore without leaving a residue, and the coating also helps keep buildup down inside a suppressor over repeated range sessions. Because it runs at true subsonic velocity, it stays quiet on a suppressed host gun while CCI’s dependable priming and consistent propellant keep it cycling reliably through semi-automatic .22 LR firearms. For anyone shooting suppressed or simply wants a quieter range day, this is a purpose-built rimfire ammunition choice.

Key Specifications

• The chambering is .22 LR, running through virtually every rimfire pistol and rifle built for the cartridge.
• The bullet weighs 40 grains, the standard weight for reliable .22 LR feeding and function.
• The bullet is a lead round nose with a polymer coating that reduces copper and lead fouling in the bore.
• That same coating can cut lead buildup inside a suppressor by a wide margin over repeated sessions, easing cleaning.
• This load runs at true subsonic velocity, keeping the sonic crack out of suppressed or otherwise quiet shooting.
• Cases are brass, a standard, reliable case material for rimfire ammunition.
• Each round costs about $0.11, an affordable price for dedicated suppressor-friendly ammo.
• The box ships at roughly 0.85 pounds, useful when figuring shipping on a bulk rimfire order.
• Each box holds 100 rounds, a solid amount for a range trip without constant reloading of magazines.

Frequently Asked Questions

Will this cycle reliably in a semi-automatic .22? Yes, CCI tunes the subsonic load’s priming and propellant specifically to cycle semi-automatic actions despite the reduced velocity.

Is this a good choice for a suppressed rimfire? Yes, the true subsonic velocity keeps it below the sound barrier, and the polymer bullet coating helps limit fouling buildup inside the can.

Does the coating leave residue like wax-lubricated bullets do? No, the polymer coating is designed to cut fouling without leaving the sticky residue associated with older lubricant systems.
