If I read correctly, the 470 Capstick is 375H&H blown out and necked up. In which case your 470 would be a perfect candidate to rebarrel to 375H&H and then rock on. A 9-9.5 pound 375H&H is just about right for my taste. Light enough to carry. Heavy enough to make recoil more of a stiff shove than a smack.
