I bought my 3 nephews there first rifle and my daughter is 5 and will be getting her first one in a year or 2. I have bought 2 260's and 1 7x57, gun weight and fit is the most important. They each got steyr prohunters with the adjustable stocks--they have grown into the guns and each now shoot something different. Look at the 6.5 creedmoor, 7-08, even the 308 is good with 110 grain bullets and a nice light charge of powder until they are ready. The styer prohunter are good rifle and can be found worth the money... My nephews were of adv size..except for one brute...I got them the mountain version with 20 in barrel.
