I have a Sako A7 in 300WSM that I will be using for deer hunting over crop fields and power line right-of-ways. I have three scopes that I've narrowed down to and was wanting some input. They are: Leupold VX-II 4-12x50 with LR; Nikon Buckmaster 4-12x50 with nikoplex ; Burris Fullfield II 4.5-14x42 with ballistic plex. I'm looking for sturdyness of the scope to magnum recoil, clarity in low light and dependability. The price ranges are from $300-$500 and am I overlooking any scopes?
