[QUOTE="sscoyote, post: 670510, member: 1133"] Exbal performs a lot of the subtension vs. magnification calcs. for you. That may be what you're looking for. Shoud be others out there that do the same as it's just an inversely proportional calculation that is used. As magnification INCREASES reticle subtension DECREASES. So you can really do all this stuff yourself. Here is a Utube that explains the concepts some-- [ame=http://www.youtube.com/watch?v=ozEhoNaRi2s]Pt. 2) More Reticle-Rangefinding Math Including 2nd Focal Plane Reticles. - YouTube[/ame] skip to 4:40.
