i started both my kids at age 5. not exactly on their birthday, but at that age, when the weather was nice and shooting would be comfortable. a big thing is making it fun for them. safety, and responsibility, is YOUR gig. no child, until they actually know what they are doing, will ever be responsible enough to shoot a firearm on their own. heck, most adults, until they have been properly "schooled", are responsible enough to shoot. my son is almost 12, i bought him his first rifle of his own when he was 7. it has now been passed down to his little sister, who is 8. this past Christmas, he got a Marlin 60. even with almost 7 years of training, i would not let him go shooting on his own, and ESPECIALLY NOT with buddies, even if it were legal. he participated in the youth hunt last fall for firearm deer, and shot a nice doe, straight thru the heat @65 yards, with my old 30-30. he has shot any gun i own, including full power 300 win mag, that he has wanted to shoot. the only 2 guns he does not want to shoot yet, is the 44 magnum pistol, and the 45-70. i do not, or will not push them into anything. but if they ask, i will let them. i hope this helps.
