I agree also, the 30-30 is by far the very BEST for what you want and for your son, and while your at it
think about why you could so easily and so quickly trade a 30-30 barrel to get a .308 or a 30-06 barrel. It's because a 30-30 will shoot just as straight, and kill deer just as dead as a .308 or 30-06 with less recoil and less expensive ammo!!! A 30-30 barrel in a Handi is almost as much of a "must have" barrel as a 45-70 or a .223, come to think of it, for a reloader, a 45-70, 30-30, .280, .223, 12 gauge barrel w/choke tubes, and a rimfire of choice you could cover any need you might ever have....<><....
