Holy cow other then the Ruger those are some nice rifles . Browning is my fav what a gorgeous rifle . I love the 700 for it's classic look and the savage is pretty nice as well .
What are you going up north to hunt ? Those are some heavy recoiling calibers you have in mind . Great for the bigger game but not so much on the older shoulder . If thats the caliber thats needed thats what you should get . It would be unfortunate if he were only able to injoy it for a couple of seasons do to it becoming more and more uncomfortable to shoot . I'm really becomming a fan of the 7mm mag . Plenty of punch with a little less recoil .
Just a thought , hope it helps .
