Between the .308 and .300WM, as long as you can shoot them equally well or close to, and other factors are essentially equal as well (rifle weight, etc.), the decision for me is easy - take the bigger bang. I don't see any downside under those circumstances.
That said, a .308 Win would have sufficed for every elk I've taken. Whether all would have dropped as quickly, no one can know - but I'm confident none would have stayed on their legs much longer..
Got a .308 for Daughter #1 for her first elk rifle, shooting 130g TTSX @ 3045fps. Upgraded her to a .270 Win with 150g ABLR @ 2912fps last year. Have a shorty 16.1" barrel) .308 Win that wighs 6.25 pound sans scope and ammo and have considered taking it, but keep reaching for my 7mm RM, a .30-06, .300WM or .338WM instead.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
