Going over for Plains Game, and had this rifle built for dual purpose as I want to use it on deer, elk in the states. I have been pouring over the internet and am thinking about a Leupold Mark iV Illuminated Reticle in 3.5 x 10 x 40. Mark IV's are 30MM tubes but seem to have a lot of dials to adjust for hold over etc which is a good thing if you have the time. I am just not sure how much fiddling around I am going to have time to do for the shot. I am accustomed to just posting a drop chart on your stock and doping the wind. Any replies are appreciated.
