CCI Ammunition Maxi-Mag .22 Winchester Magnum Rimfire 46 Grain Segmented Hollow Point Rimfire Ammo 50 Rounds. New Maxi-Mag Segmented HP uses an exclusive polymer bullet coating to greatly reduce copper and lead fouling in the barrelwithout leaving a residue. It also cuts lead buildup in suppressors 60 to 80 percent. The load's 46-grain Segmented Hollow Point splits into three equal-size pieces on impact tripling the number of wound channels. The polymer bullet coating allows this separation at much lower velocities and longer distances than a conventional copper jacket. The bullet's overall geometry is optimized for accuracy and dependable CCI priming and propellant provide flawless cycling through semi-automatics and all 22 WMR firearms.
