Just about everything you have will work. I prefer a 300WM, but also have a 308 as my backup. Since my first elk trip in 1996, I haven't taken a shot at elk past 140 yards or so. I like the comfort of knowing I could take a 400 yard shot if that was all I had. My advice is not caliber related; I think way too much time is spent on worrying about caliber. Get a good solid copper (TSX) bullet in whatever caliber suits you and move on. My number one piece of advice for new elk hunters is GET IN SHAPE. The mountains will kick your ass, it hurts less if you're in shape. In terms of a rifle, go for something stainless and under 8 pounds with an optic, sling, and full magazine.
