1)22 don't have "stopping power"
2)I used CCI Stingers for MANY years as my primary choice hunting woodchucks. They performed marvelously.
3)100 yards with a 22?... I don't know how'd you "know" that 5 out of 5 of those shots hit, particularly since one would assume that the animal was not holding still after a single hit. 5 shots, off-hand, at 100 yards, with a 22, hitting a target the size of a skunk would be... remarkable.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
