There are a million good elk cartridges to include your 308 which have been written about at great length. Looking at my load for a 300 WM with 180g bullet v my 30-06 with a 165; both zeroed to be 2.5 high at 100. The 300WM gets you about another 25 yards before you reach a foot of drop and thats between 375 and 400 yards. I think the truth is, for the animals you want to shoot, it's really about taking afield the rifle/cartridge combination that you really want to use. If it's a 300 WM, great, if its something else, thats just as great. You are kind of in that "cant go wrong" area but if you do, you can change.
