Check out some of the videos on YouTube to see the Ruger SR 22 shoot through every cheap brand of 22 cartridge found on store shelves.
I can use whatever .22 round I want in my .22 rifles. For the pistol, however, I need very high velocity .22 ammo (such as CCI MiniMag). Without the high velocity round the slide will not cycle back because it is a full weight slide.
