Heh... yeah, and buddy of mine severly pissed of a squirrel with a .22 load of that.Yep, rat shot. I've shot the .22 in my GSG. they do not cycle the bun but you can shoot them one at a time. They wont go through a coragated cardbord at 15 ft. I'm sure the .40 and .38 are more powerful. I heard that .22 shotshells were great for hunting dragonflies.
