CCI Maxi-Mag Rimfire Ammunition .22 WMR 40 gr TMJ 1875 fps 2000/ct Case (40-50/ct Boxes)

The CCI Maxi-Mag rimfire ammunition in .22 WMR delivers solid performance for shooters who want reliable, consistent rounds at the range or in the field. This 40-grain total metal jacket load pushes 1875 fps from the muzzle, giving you the velocity needed for accurate hits on small game and varmints. With 2,000 rounds per case (packaged in 40–50 round boxes), you're stocking up on ammunition built with CCI's reputation for dependable priming and consistent brass—the kind of fundamentals that matter when you're logging hours of shooting.

The TMJ (total metal jacket) bullet design wraps a copper jacket around the lead core, reducing fouling and helping you maintain accuracy across a high-volume shooting session. Whether you're working through practice rounds, testing a new .22 WMR rifle, or keeping a varmint rifle fed, Maxi-Mag gives you the volume and reliability to focus on your shot, not your ammunition.

CCI has been the go-to primer and ammunition maker for rimfire shooters for decades. Maxi-Mag is their answer for shooters who need more power and velocity than standard .22 LR, without the expense or recoil of a centerfire cartridge. The bulk case format makes sense for anyone running volume through their .22 WMR platform.
