CCI Maxi-Mag .22 WMR Shotshell Rimfire

CCI Maxi-Mag .22 WMR Shotshell is a unique specialty rimfire cartridge that uses a .22 WMR case loaded with a small-shot charge rather than a conventional bullet — creating a miniature shotshell effect for pest control and snake shot at very close range. The .22 WMR case's larger capacity compared to .22 LR allows a more effective shot charge than .22 LR shotshell alternatives.

At ranges under 10 feet, the Maxi-Mag Shotshell is effective for snakes, rats, and pests in grain stores, outbuildings, and tight spaces where a rifle bullet would be dangerous. It requires a firearm chambered in .22 WMR — do not use in .22 LR firearms. The 10-round packaging reflects the specialty use case where only a small number of rounds are needed per session.
