excellent!
my oldest daughter turned 6 in august, and i bought her a youth 22 to get her started. she really enjoys it!
i was doing some range work w/ my ar-15 one day and she was very insistent on trying it... i let her run a couple down the pipe, but she didn't care for it - too loud, too much recoil. that's ok... we'll enjoy the 22's for awhile yet.
