At the beginning when I first posted the origional question, my pushing the bush deer rifle was a Marlin 336 in 30/30. I have since then, kind of went on a spending and selling spree.
My new gun is more of a Hybrid, that will be used for the tree stand, and for pushing the bush. Its a Tikka T3 Lite Stainless, in 30/06. I have a Burris Fullfield II 3x9x40 scope on it with flip up lense covers. When the scope is set on 3x Zoom, its very easy to pick up a close target, or a moving target. The gun is super light also, and I can get a 5 round extended magazine, so if I am having problems hitting something on the run, I will get lots of chances at it.
