My daughter turned 12 last summer. She's been shooting with me the past couple summers. I started her off this summer with my 22 mag. Then I had her cracking my 30-06. After that we moved up to my 300 RUM. I let her decide how many rounds she wanted to shoot out of each. She didn't hesitate to shoot the RUM once she got comfortable with it. In Oct she smoked a nice antelope and followed it up a couple weeks later with a nice 5x7 bull elk at 240 yards.
