[QUOTE="sscoyote, post: 516455, member: 1133"] Yeah Marc, it is. Suppose u look at your verified "dope" and it says that at 475 yds, u need 5 moa of "holdover" (trajectory compensation) from whatever your zero is. U just holdover 5 of those little 1 moa marks in your scope... but if it were me i'd calculate, test, and troubleshoot the ballistics programs zeros in MOA for the optic's highest power (~.75 MOA @ 24x). Then recalc the holdovers in 50-yd. intervals for easier interpolation. I.e. suppose u need 4.8 MOA holdover for 550 yds. that's 6.4, .75 MOA marks (4.8/.75=6.4). Now if u want to use the optic at a lower power adjust the power to 12x, and just halve the holdover reference (assuming the scope is ~accurately cald. for power) . U could easily put that dope into a Butler Creek scope cap cover with the addtl. 12x reference info as a short concise notation like say (12=1/2). [/QUOTE]
