Just want to add that a .308 Win compared to .30-06 is like comparing two likewise apples. The animal won�t notice any difference. No matter what distance you shoot at. The unnoticeable trajectory difference, does not exist if you practise enough. And the energy punch is too small to even be mentioned (sorry for mentioning it). And oh yes, not to forget, no problem to put a 220 grains bullet in a .308 Win.
