i took the time to ask Kodiak. Is the logic here sound? i'm but a simple man who wants to plink @ 100,50,25 with irons first and ACOG one day if budget and Turdeau allows. ... wouldn't something like a CZ EVO sight bridge the height problem?
1)" The difference between the rails from the 180C to the 180NSR is 11.24mm or a little less than ½”. Assuming a zero at 200 metres, the difference is slightly more than 1/20 of one Mil or a little less than ¼ MOA. If we shoot using that zero at four hundred metres, the amount the sight would be out is about an inch. (I’m doing the math as I type on a post-it so maybe don’t quote me, but I’m pretty sure I’m doing it correctly.)" I'm not shooting comp so i'll leave that 2)Sight graduations are approximations only. When shooting competitively, no shooter worth his salt is going to use pre-set range adjustment knobs. When doing higher end things using an optical sight, we typically shot “open gate.” (That is to say that we opened the adjustment gate, zeroed at 100, at 200, at 300, at 400, etc., and marked each spot on the dial with a grease pencil; ignoring the 2, 3, 4, etc. marked on the sight.) The bullet drop will also vary between brands of ammunition and bullet weights so it adds more variables to the equation. (ie what ammunition is your sight graduated to?) If accuracy is a deal, you shouldn’t be relying on the pre-sets anyway."
