Gentleman, how do I go about measuring the scope height for input into a ballistics program. I have a stock standard Rem Sendero in 300 RUM, with medium Badger rings and 20MOA picatinny rail. I have doubts as to where I should measure because of the 20MOA incline on the rail. From what I can see on the ballistics charts there seems to be a very small effect when changing scope height in a ballistic table. Can one make an assumution on the scope height i.e. 1.77" and will this still be accurate out to distances of 750yds if you're off by 0.2" ?
