I dearly love my 30-30 Winchester in the Adirondacks but for a cleaner and quick kill on a whitetail deer or black bear my sporterized Lee-Enfield with hard to find 225 grain bullets can't be beat though the 170's aren't too bad - I had some odd ball 190's at one point as well but have never seen another box since. An -06 is as good if you choose your ammunition well - about the same velocity but a bit less energy in factory loads
