[QUOTE="sscoyote, post: 952062, member: 1133"] What you may want to do with that reticle is to range a bunch of targets at different distances and then recalculate the actual subtension (the 2 MOA units) from those readings, i.e. say a 10" target at 223 yds. occupies 2.3 2 MOA units, then the equation becomes-- 10 x 100 / X / 2.3 = 223 X=1.95 inches @ 100 yds. ...now do 10 more or so and "reverse-mil" (as above) the subtension, average it and just use that as your "useable" subtension factor in the equation. I have found that most reticle-ranging falls apart beyond 500-700 yds. or so depending mostly on size of target relative to subtension unit, magnification, and resolvability. [/QUOTE]
