The 10FP that my Police Dept. issued me has a Leupold 3x9x40 tactical, Farrell base and rings. The elevation adjustment tops out at about 800 yards. A friend has the scope you are looking at, Zeiss Conquest, on a PSS 308, he can get about the same yardage. I just put together my own 10FP, money is a little tight right now with the wife sick so I went with a Sightron 4x16x42 MD and a 20MOA Farrell base hoping to get to 1000 yards. Haven't shot it yet. Point is, if you plan to shoot to 700 yards a 1" tube will normally do the job, if you want to shoot farther then go with a 30mm tube or a canted base. That Zeiss is a nice scope.
