I used one for years on my 270.... it will do a fine job and give a nice wide fov in the close up/hip pocket woods hunting situations. Not much diff in the 3x9 cept the 3x9 will help if you shoot really long distances. I made multiple 300-325 yd kills with my 2x7 though. I have that exact 2x7 Pro-Staff on a 7-08 now and that is my go to deer gun and scope.
