[QUOTE="Broz, post: 1150678, member: 7503"] Yes, I agree with what you are saying. But please read what you quoted from my post again. What I said was again "With 100 yard zero..... [B]the Line of sight Difference is more like 1.5 moa[/B]" You say 1.75" . That is line of sight above barrel bore. Right? I didn't mention drop or bullet path. My math, 1 moa at 100 yards is 1.047" x my 1.5 moa that equals 1.57" so dependent on our scope height your examples are .180" of an inch above mine. less than one click.:) I agree with your calcs for dial up after. But have mounted a bunch of Nightforce NXS's in .885" rings over a NF 20 moa rail and got the full 70 moa. of elevation from the 100 moa scope. Or within a click or two. However I realize it could go the other way too. Thus the reason I stated more than once "In a perfect world" which we all know is not the case. You well know that those 3.5 moa you are talking about could very easily be added to the dial up too if the rear of the receiver is a little high or the rings a few thousands off or what ever of the many errors that come into play. No, its not a perfect world, but the error could just as easily go towards 3.5 more dial up as less. Jeff [/QUOTE]
