.22 Mag has been a favorite of mine for close to forty years. A great turkey rifle (when it was legal). Ammo was the sole problem with the .22 Magnum for years. The best choice for accuracy until a few years ago was the RWS load (about $25 a box). The Remington Premier 33 Grain V Max or the CCI 30 grain polymer tip will kill crows or woodchucks out to about 125 yards with ease.
