I am looking at the same thing myself for my son who will be 10 next week. I just wonder how accurate these would be when you swap the barrels out?

A rifle that I have been giving serious thought to is the Weatherby Vanguard Youth in .243 Win. It comes in a youth size stock but also comes with a full size adult stock for when the kid gets bigger. I think that would be a better quality rifle but would be more expensive up front and you would still need some type of .22 for "plinking".
