The .22 Winchester Magnum Rimfire (WMR) can be used for varmint control, small-game hunting, and even self-defense. Famous for its light recoil and effectiveness, .22 WMR ammo will remain an excellent choice for years to come.

The .22 WMR uses bullets comparable in weight to the .22 Long Rifle, but is considerably faster, it shoots flatter and farther and hits harder at all ranges.

22 mag ammo, also commonly called 22 Winchester Magnum Rimfire ammunition is a rimfire cartridge introduced by Winchester in 1959.

The limited selection of commercial ammunition for the .22 WMR has inspired specialist wildcatters to select the .22 WMR case for handloading high-performance rimfire ammunition.

Generally, they load the wildcat cartridges with pointed bullets for the aerodynamic advantages, using the same shots like those in .22 caliber centerfire cartridges. 

Though such weapons are generally heavier than standard .22 WMR, the sharp nose and tapered tail conserve energy better, delivering a more significant impact at longer ranges.
