I took gun safety classes at 12 or 13 I think, I grew up around rifles, shotguns mostly. couldn't hit a damn thing if I tried... but I scared a lot of game.
My dad gave me a 22 single fire Mossberg at the age of 6. He trained me carefully and made certain that I did not point it at anything that I did not intend to kill. That rule applied wether the rifle was loaded or not.
I shot countless thousands of rounds and graduated to the high power class by the age of 12.
After I went into the service, it was needless to say how well I qualified in Basic Rifle Marxmanship. I owe my lif to my Dad. That shooting ability kept me alive in Vietnam.
