CCI 958 Maxi-Mag 22WMR 40gr JHP Varmint Ammo 200rd Box

The CCI 958 Maxi-Mag delivers devastating terminal performance on varmints with its 40-grain jacketed hollow point design optimized for maximum expansion. This premium 22 Winchester Magnum Rimfire ammunition transforms bolt-action and semi-automatic rifles into precision varmint control tools. Each cartridge generates consistent velocities that maintain flat trajectories out to extended ranges where prairie dogs and ground squirrels present challenging shots.

What Makes This Different

CCI's Maxi-Mag construction features a precisely engineered hollow point cavity that initiates rapid expansion upon impact while the jacketed design maintains structural integrity during flight. Standard 22WMR loads often fail to expand reliably at longer distances, but the 958's optimized bullet profile ensures consistent performance from 50 to 150 yards. The 40-grain weight provides an ideal balance between velocity retention and energy transfer for varmint-sized targets.

Key Features

• 40-grain jacketed hollow point bullet optimized for varmint expansion
• 22 Winchester Magnum Rimfire chambering for extended range capability
• Muzzle velocity of approximately 1,875 fps from 6-inch test barrel
• Clean-burning powder formulation reduces fouling buildup
• Non-corrosive priming ensures reliable ignition in all weather conditions
• Brass cases suitable for reloading applications
• 200-round bulk packaging reduces cost per shot for high-volume shooting

Field performance demonstrates exceptional accuracy from quality rimfire rifles, with many firearms achieving sub-2-inch groups at 100 yards. The hollow point design transfers maximum energy to small game and varmints while minimizing over-penetration risks in agricultural settings. Hunters report reliable expansion on prairie dogs, ground squirrels, and similar-sized pests at ranges where standard 22 Long Rifle ammunition lacks sufficient energy. The consistent ignition and velocity make this ammunition suitable for both bolt-action precision rifles and semi-automatic platforms.
