I really feel that the last 2 to 3 clicks, maybe more, are not in tune with the rest of the elevation grid. I also feel if you hit the bottom, even being careful, it can cause you to move your zero. So my advice here is to set the zero at least 1 moa off bottom with a zero stop to protect the internals.
Not sure if he does it for the same reasons or if it is just coincidence, but I have noticed Shawn Carlock seems to stay away from the extreme top and bottom of his dials too. I never asked but just felt he has the same experiences I have had.
Hi Jeff all you need is a rail with enough angle in it so that at your desired sight in distance you have less than 20 moa underneath, then there is no way you can use the wrong zero.
Having 20 moa dials has made this much easier to acheive.
I agree that running the scope right at the top & bottom of its travel should be avoided if possible as well as being "rough" when operating in those areas.
