I need a scope for a Remington 700 vs sf II in 223 rem. I want I gues around a 6.5 X 20 X 40 . I want target knobs and a mil dot but I am concerned about how much adjustment I will need. I was looking at the Zeiss, IOR, Leupold and maybe Nikon Monarch. Paper and prairie dogs will be the targets and occaisional coyote. All comments welcome. Thanks
