RE: guns
I agree with most here in that up to a 30-06 should be all you need. It's all I've ever hunted with........and a side note (don't know if others feel the same).......after all the deer I've shot.....not once have I felt the recoil!!
Choose a gun you're comfortable with and which suits your style of hunting. I walk a lot, which is why I would never get rid of my Husquavarna.....very light and easy to handle.
Hope this helps!
