There is some controversy, here on the 'Fire, as to whether a "Timber Elk Rifle" is even a valid concept. Plenty of guys think that your regular rifle is your timber rifle.
I am in rikt300's camp... a short, easy handling rifle with plenty of oomph is a good thing in the woods. If it is a fast repeater, so much the better. This is not a necessity, just a nicety.
