I realize that I am stating the obvious, but it is a hell of a thing when a man has to worry about how "legal" giving his grandson a .22 is.
Leaves a bad taste in a fella's mouth.
amen. it is perfectly legal to buy a gun and give it as a gift.
as far as the youth gun question, it is perfectly legal for folks under 18 to own a gun. they just cant buy them. you must be 21 to buy a handgun in wisconsin, but may own one if your 18. hey, dont ask me; i dont write 'em, i just follow 'em. 
From the Texas Penal Code:

I remember hunting solo with a .22 when I was 10 years old.
Looks like the issue is adult supervision. I mean, it's like, "for the children".
Maybe my mother just didn't care.
