Zero 6" above point-of-aim at 100 yards, and impact will be very near to 6" above POA at 200 yards. Or, if zeroed for 3" above POA at 100 yards, elevate 3 MOA for 6" high POI at 200. (IIRC that would be about 3 clicks on the Mk1 leaf.) Table calculated for 180 Sierra @2470 fps. MkVII should not vary significantly. Note "Path" column, which gives deviation from line of sight.
