I have always used a 7mm or 300 mag. but the 338 was designed with elk in mind. In lodge pole pines or any thick cover I would pay homage to Elmer and take the 338. Any will work fine if you don't push them too far. Otherwise I would pick the lightest one. A 308 carbine with a 165 Barnes is pretty handy.
JK: On the prep flush out the trigger with lighter fluid and only wax the external surfaces. Something like Corrosion X might be light enough but I trust the lighter fluid only more if temperatures are likely to be low. I have had a dud even when the temperature were in the teens, this was due to a bad primer strike, so when I flush the trigger I do the firing pin spring too.
