Applications
The .22 WMR is effective out to 125 yd (115 m) on varmints such as fox or coyote. When loaded with hollow-point bullets, it is too destructive for small game (under 50 yd ), such as rabbits or prairie dogs or anything intended for eating.
In 2011, Speer released a .22 magnum version of their Gold Dot Personal Protection ammo, and Hornady of their Critical Defense ammo. Both are optimized for the short barrels found in self-defense handguns. Both are made for self-defense.
