CCI Maxi-Mag 22 WMR ammunition delivers the performance you need for everything from small-game hunting to competitive rimfire shooting. Each 50-round box contains 40-grain Total Metal Jacket (TMJ) rounds engineered for reliable feeding and consistent shot placement. CCI has built its reputation on producing dependable rimfire ammo, and this .22 Winchester Magnum load reflects that commitment to consistency and quality.

The TMJ bullet construction ensures smooth cycling through your rifle while minimizing fouling—a practical advantage whether you're punching paper at the range or working through a day of plinking. With a muzzle velocity of 1875 fps and muzzle energy of 312 ft-lbs, the Maxi-Mag strikes a balance between speed and controllability, making it well-suited for shooters who value accuracy without excessive recoil or noise.

22 WMR has earned its place among serious rimfire competitors and recreational shooters alike. It offers noticeably more power than standard .22 LR while remaining affordable and manageable in any .22 Mag rifle. The consistent rimfire casing and primer quality you expect from CCI means you can focus on your technique, not on equipment variables.
