I'd also go with a 44mag with full power loads. For hiking, I'd stick with a shorter barrel, it comes out quicker and is lighter to pack. A S&W Mountain Gun(4-inch), any Ruger in 5 1/2 inch(Blackhawk or Redhawk) or a Colt Anaconda 4-inch will do fine. For hunting, I like a longer barrel(6in or longer) in 44mag or bigger.
