Well, my daughter is 13, I'm about 5' 8'' and she is almost as tall as me. She shoots my old marlin 336 in .35 remington with 200 grain bullets, she killed her first deer last year, and her second one this year both one shot kills. Both with me sitting beside her!She's also getting an 870 youth model 20 gauge for Christmas, she just doesn't know it yet. My son is only 5 and I don't know for sure when I'll start letting him use an actual firearm. He currently shoots a daisy bb gun lol. I started my girl out shooting with a lever action .22 to get her usedto using a scope, and when I moved her up to the .35 she drilled a 2 inch bull at 100 yds, and that gun only has a 4 power scope on it. That's irrevelant to this topic, I just wanted to brag on her a little bit.
