Could someone please help me in a way to figure my reticle substensions when I change magnification on my scope?? My scope is a NF 12x42x56BR. It has 40 MOA total elevation. Reticle is NP1-RR. Scope has dots at 4moa,8 moa, 15 MOA, and 20 MOA. The ranging shows correct for 22x on the scope . My question is how can I figure out (besides shooting it) where the dots would be on say 32x or 42x?? . After a 100 yd zero I have 26.4 MOA left in the scope. Enough to shoot 600yds but not 1000 yds. What I was going to do was use the dots as holdovers but want to increase my magnification past 22x. Attached is a picture of the reticle. Any and All help would be greatly appreciated.
