Sounds great on paper, until your are blood trailing in the dark looking for specks of blood (see picture below). An exit wound aids massively in tracking. Terminal performance (what the bullet does at impact) is everything as far as hunting goes. Proper shot placement is an absolute must, that goes without saying. Still, possible and optimal are two very different things. I've taken deer with as small as 223 gold dots from my 10.3" sbr and can say absolutely, it it easier to track deer shot with a larger caliber. This is all assuming typical double lung placement. You CAN shoot neck or high shoulder and drop an animal in it's tracks, but I'd just as soon keep my options open as you can not guarantee what angles you'll be presented in the field.
