What type of ammunition should I use in my Ruger .22 pistol?
The Ruger .22 pistols are chambered only for the .22 caliber Long Rifle cartridge, standard velocity or high-velocity, manufactured to U.S. Industry Standards. Do not attempt to load hyper velocity, .22 Long, .22 Short, or any other type .22 caliber cartridge into the magazine or in the chamber of the pistol. Use of .22 shot shells is not recommended.
