Thread: Does a spotting scope need a reticle to be useful for long range shooting?

I have been considering investing in a spotting scope. Can all of you that pursue long range target shooting tell me whether a spotting scope needs to have a reticle with for example mil dot graduations to be useful? I have been developing my ability to call from fall of shot onto target and have been thinking about greater magnification than my rifle scope gives but have considered that if I cannot measure (such as with mil dot graduation) then there is not much point to it. Your thoughts appreciated
