RE: .270 or 30-06?
Aside from dangerous game (large bears) and bisonI would hunt anything on this continent with either one to the same yardages.
I have both of them and neither one show a distinct advantage over the other.
Having said that, I am partial to the .270 simply because it has a slightlyflatter trajectory.
However, since you are hunting in thick woods andaren't shooting at any great distances I would look real hard at the .308 or the 7mm-08.
