RE: One Rifle
If you buy factory ammo then the 7mm rem, 3006 or 308winwould be my vote. If a reloader then the ones listed prior will work fine as bullets can be found to load up or down for the application.
If your daughter will be shooting it only off the bench and bags you may want to consider a heavier rifle vs a lite/ultra lightset upto help with felt recoil. Of course being it is your hunting rifle you still must consider your needs too. What ever you choose install a sims limbsaver, pachmayr decellerator, etcrecoil pad(if not already equipped on the rifle), this will help both you and your family with handling the recoil the rifle puts out. The SPS is a good suggestion and comes equipped with a sims pad (R3). Though like you said have to do some looking to find the right one for you.
Good Luck
