Not to say it isn't true either, but I don't buy the whole start them off young with a heavy caliber and muscle memory thing. My boy has a small frame so I want to get him a pleasant rifle to start off with that he will enjoy shooting along with getting his first deer. Heck, I may just save the money, let him use my 30-06 with managed recoil rounds, and better use that saved money on a bow. He's expressed interest moreso in bow hunting so it wouldn't be a bad thing for me to start learning. I bow hunted once when I was 16 so it shouldn't take long to re-learn it. Cool.
