New CCI CLEAN-22 Lead Fouling Reducing Rimfire Ammunition

    CCI Clean-22 1

    CCI has announced about the release of their new Clean-22 rimfire (.22 LR) ammunition which is specially designed to reduce the lead fouling and build up. While everyone will benefit from this feature, it should be especially important for those of you who shoot suppressed rimfire guns.

    Below you can find the CCI’s press release.

    LEWISTON, Idaho – February 15, 2019 – CCI Ammunition is proud to announce new Clean-22— ultra-clean rounds that represent the future of rimfire shooting. Shipments of Clean-22 are being delivered to dealers.

    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.

    Features & Benefits
    • Polymer bullet coating greatly reduces lead fouling in the barrel without leaving residue
    • Cuts lead buildup in suppressors 60 to 80 percent
    • 40-grain lead round nose bullets — red for High Velocity, blue for Sub-Sonic
    • Optimized bullet geometry for improved accuracy
    • Reliable function in semi-automatic firearms
    • Great option for both casual and competitive shooters

    Part No. / Description / MSRP
    934CC / Sub-Sonic 22 LR 40-grain blue poly-coated LRN, 1070 fps, 100-count / $9.95
    944CC / High Velocity 22 LR 40-grain red poly-coated LRN, 1235 fps, 100-count / $9.95

    60 to 80% of lead fouling reduction! Earlier CCI released rimfire ammo with coated bullets but back then the fouling reduction rate was stated to be 30-40%. If the Clean-22 works as advertised then it should become the best rimfire ammunition for use with suppressors.

    As seen in the press release, there are High Velocity and Subsonic version of this new ammo. Below you can see the velocity, energy and trajectory data of both loads.

    I wonder if one can achieve similar results by powder coating the .22 LR bullets using the commercially available powders such as those made by Eastwood or Harbor Freight. Even if you can, rimfire ammunition is normally considered non-reloadable. Well, I should say hard and not cost effective to reload because technically, you can reload it using Sharpshooter Rimfire Reloader tool kits.

    I think, coated bullets are the next step in the evolution of rimfire ammunition. Do you think that rimfire ammo with polymer coated bullets will start dominating the market in the foreseeable future?
