My 12 yr old started on a 357 mag Handi about 2 years ago. He still shoots it regularly, and hunts with it. 38 special for practice shooting, and 360 DW for serious stuff. He is really small for his age, he's just about the size of an average 10 yr old now. At 100 yds., he can wear a 6 in. bullseye out. I think the 357 is the best starter for a kid, and when he gets a bit bigger, 30-30. At least it's worked out great for us.
