I own both and have shot them quite a bit as well--in my case the .458 Win definetly has more recoil than the .416--having said that--the stock, weight of the rifle, how it fits you will also make a HUGE difference..
It is quite apparent when shooting different double rifles in the same caliber .. not all guns are created equal nor do they fit equal..
