The CCI 958 Maxi-Mag is purpose-built ammunition that puts varmint hunters right where they need to be. With 200 rounds per box, this load pairs speed with accuracy for field work where performance matters. Each 40-grain jacketed hollow-point bullet travels at 1,875 fps with 312 ft-lbs of muzzle energy, giving you the velocity and stopping power needed to take down ground squirrels, prairie dogs, raccoons, and similar-sized game efficiently.
CCI's reputation in rimfire ammunition shines through in every aspect of this load. The clean-burning propellants keep your rifle's action cleaner during extended shooting sessions, while CCI's sure-fire priming ensures consistent ignition round after round. The brass casings hold up well for shooters who reload, and the careful powder selection delivers consistent chamber pressures that translate to predictable ballistics downrange.
The 40-grain jacketed hollow-point design creates the kind of terminal performance varmint control demands. The hollow cavity promotes controlled expansion on impact, while the copper jacket maintains integrity through light barriers like brush and hide. This combination ensures the bullet transfers tremendous energy to the target without over-penetrating, keeping shot placement effective and clean.
Beyond varmint hunting, this ammunition works for target practice and plinking when you want to put in serious trigger time without breaking the bank. The flat trajectory at typical rimfire ranges makes it easy to dial in your scope, and the consistent performance means your dope stays good. Made in the USA, the CCI 958 is backed by decades of rimfire ammunition expertise.
Yes, the CCI 958 is designed to cycle reliably in semi-automatic rifles and handguns chambered for 22 WMR. The clean-burning propellants and consistent powder charges support dependable operation across different firearm platforms. Real-world field use shows strong reliability in rifles like the Kel-Tec PMR-30 and similar platforms.
The 40-grain jacketed hollow-point is designed for ground squirrels, prairie dogs, rats, raccoons, and similar small to medium varmints. The 1,875 fps velocity and 312 ft-lbs energy deliver the performance needed for quick, clean kills on these target species. It's significantly more powerful than 22 LR ammunition while remaining mild in terms of recoil and report.
The 40-grain bullet maintains more than 75 percent of its velocity at the 75-yard mark, delivering a relatively flat trajectory for rimfire standards. This makes it capable at extended ranges compared to 22 LR, though dedicated precision shooting at extreme distances may benefit from lighter-recoil specialty loads. The 1,875 fps velocity and 0.116 ballistic coefficient keep it in the game at typical field distances.
Yes, the brass cases are suitable for reloading. CCI brass is known for good quality and durability, making it popular with handloaders who want to customize their loads or stretch their ammunition budget over time.
