RE: Rifle for youth
My son has a Youth Model 7 .243. After shooting it, I liked it so much I got a Model 700 .243 for myself. Makes the logistics easier... We only have to grab one box of shells when we head out to the lease. Don't rule out a .243 for him just because you already have one. It's anice cartridge. Recoil is quite a bit less than the 25-06 and that seems like it would be a significant factor if you're getting a rifle for a 9 year old.
