CCI 0023 Maxi-Mag 22WMR 40gr TMJ Rimfire Ammo 50rd Box

The CCI 0023 Maxi-Mag delivers consistent terminal performance in 22 Winchester Magnum Rimfire with clean-burning propellants and reliable ignition. This 40-grain Total Metal Jacket ammunition provides excellent accuracy for varmint hunting and target shooting applications.

What Makes This Different

CCI's Total Metal Jacket construction completely encases the lead core, eliminating lead fouling in the barrel while maintaining consistent ballistic performance. The clean-burning powder formula reduces residue buildup compared to standard rimfire loads. Velocities reach approximately 1,875 fps from rifle-length barrels, delivering flat trajectory and retained energy at extended ranges.

Key Features

• 40-grain Total Metal Jacket bullet eliminates lead fouling
• Clean-burning powder reduces barrel residue and fouling
• Consistent muzzle velocity around 1,875 fps from 20-inch barrel
• Reliable CCI priming system for consistent ignition
• Brass-plated cases for smooth feeding and extraction

Field testing demonstrates excellent accuracy potential in quality rimfire rifles, with many firearms achieving sub-2-inch groups at 100 yards. The Total Metal Jacket design maintains bullet integrity through various barrel twist rates while providing clean entry wounds for small game hunting. Weather-resistant case coating prevents corrosion during storage in humid conditions or temperature extremes.
