sometimes, and 99% of the time for me, it isn't about killing anything.......i just enjoy shooting.......i've only hunted once in my life but i sure love to shoot my guns.....
i think it's great that he's doing it correctly.....my daughter will be 5 in a few days, i'd say i could do this same thing and she'd be attentive and i know she'd remember EVERYTHING i say (she has a great memory.....like her mother!

)
my son, on the other hand, is only 2 and he's a lot like me...can't pay attention for more than 2 seconds, hyper, etc.....at the rate he's progressing, now, there's no way i'd introduce him at 5.......it's a judgment call......
i bought my daughter a small atv last fall......i put her on it, with a helmet....she did great but had a hard time with the brake handle......she rode around quite a bit over several days.....i had it where it would barely pull it's self.....one day she made a quick turn and it slowly tipped on it's side and bucked her off....she cried, scared me to death......i encouraged her to get back on.....after an hour or so, she was right back on it......but, i put it away and haven't brought it back out for about a year......she's back on battery powered stuff, for now.....
Yeah, what's wrong with starting youngsters out on a bbgun, then a pellet rifle. I don't get it. Don't know what a 5 year old can kill with a 22 that he can't kill with a bbgun, without 40 grains of lead ending up a section over.
