22 Mag Ammo

Introduced in 1959, the .22 Mag (also known as the Winchester Magnum Rimfire or WMR) is widely used for varmint hunting. It fires a relatively light 30-50 grain bullet at a high muzzle velocity of approximately 2,000 feet per second. This produces better medium-range external ballistics than the .22 LR. On the terminal side, the higher velocity of the projectile results in faster expansion or fragmentation with appropriate bullet types, with superior results against small game.

While not as widely produced as target-oriented rimfire calibers, .22 WMR ammo can be had from a variety of manufacturers at a reasonable cost. CCI TNT and Hornady V-MAX fragmenting hollow point ammunition works well for varmint hunting. This caliber is sometimes used for compact concealed carry, although its effectiveness is limited in this role.
