[QUOTE="sscoyote, post: 655226, member: 1133"] Pretty good Load--I also like to play with the math behind reticle rangefinding. As it turns out the equation actually defines the reticle and turret reference for downrange zeoing as well. I apply the mil-ranging formula with any reticle subtension, from simple plex to Ballistic Plex and anything in between. Here's the formula i use-- tgt. size [inches] x range of reticle subtension measurement [yds.] / reticle subtension [inches] / "mil-reading" = range [yds.] It also helps to know that reticle subtension is inversely proportional to magnification in 2nd focal plane scopes as u noted above. Here's a couple youtubes i did on these concepts since they're way bigger than simply mil-dot ranging and downrange zeroing-- [ame=http://www.youtube.com/watch?v=iNvJKBOpj08&feature=relmfu]Pt. 1) Reticle-Rangefinding Math - YouTube[/ame] [ame=http://www.youtube.com/watch?v=ozEhoNaRi2s]Pt. 2) More Reticle-Rangefinding Math Including 2nd Focal Plane Reticles. - YouTube[/ame] [/QUOTE]
