Perfectly fine if you have the elevation you will need available. The scope body markings are for the total available travel for the scope without any zero stop. Once you add in the shims for the zero stop, you are limiting the the travel of the turret so it will not be able to go lower. In the ideal world, you are towards the middle or lower end of the range when you are zeroed. This leaves the most amount of travel available. Likewise, distortions can occur at the extremes due to the internals design. I have a gen I 2.5-10 on my hunting rifle that is around the 4. Works for me though as I can get the range out of it I need and don't have any real distortion or tacking errors, and don't need more than I have available.
If you are really concerned about it, you can get a scope base with more angle and that would allow you to take some shims out and dial lower on the scope body.
