22 Win Mag, or 22 Winchester Magnum Rimfire, is a rimfire cartridge that was introduced by Winchester in 1959. It is a high velocity round that is designed for small game hunting and target shooting. The cartridge is based on a modified version of the .22 Hornet case, and uses a bullet with a diameter of .224 inches. It has an effective range of up to 150 yards, making it suitable for varmint and predator hunters. The 22 Win Mag is widely used for pest control, as well as for plinking and small game hunting. It is also a popular choice among competitive shooters and backyard marksmen due to its accuracy and affordability. The round has been chambered in various rifles and handguns, including the Ruger 10/22, Savage Model 42, and Taurus Tracker.
