Since elk are in the mix, I'd opt for the 7-08. Aside from that, I have both and hunt with both. their performance on deer sized game is basically the same. Kinda like the difference between a 7mag and a .300WM.
I use 140gr bullets in both of them so that may be a factor. Once you're in the 2600-2900fps bracket, gaining a 100fps by going to a lighter bullet is kinda pointless IMO.


Aim for the exit hole.
