Also known as .22 Magnum, the .22 Winchester Magnum Rimfire cartridge delivers increased velocity, energy, and range compared to traditional .22 LR ammunition, making it a favorite among hunters and recreational shooters alike.

Introduced in 1959, .22 WMR quickly earned a reputation for exceptional rimfire performance. Its higher velocity and flatter trajectory provide shooters with improved effectiveness at extended distances, making it ideal for small game hunting and pest management. Many hunters rely on .22 Magnum for rabbits, coyotes, prairie dogs, foxes, and other varmints where legal.

Modern .22 WMR ammunition is available in a variety of bullet designs including jacketed hollow point (JHP), full metal jacket (FMJ), polymer tip, and specialty hunting loads. Popular bullet weights typically range from 30 to 50 grains, allowing shooters to select ammunition optimized for expansion, penetration, or target performance.

Shooters appreciate .22 WMR for its balance of increased power while still maintaining relatively low recoil and affordable operation compared to centerfire cartridges. The cartridge remains popular among ranchers, hunters, and outdoor enthusiasts seeking dependable rimfire performance in the field.
