The future of rimfire is here. CCI® Clean-22® uses an exclusive polymer bullet coating to greatly reduce copper and lead fouling in the barrel—without leaving a residue. It also cuts lead buildup in suppressors 60 to 80 percent. Both the Sub-Sonic and High Velocity loads feature a 40-grain round nose lead bullet with geometry that’s been optimized for accuracy. With dependable CCI priming and consistent propellant, Clean-22 provides flawless cycling through semi-automatics and all 22 LR firearms.
