No problem Mark. Glad to be of some help. Another advantage to the system is that u can calculate any of the unknowns in the equation once the other variables r known--"reverse-milling" as it's called. At a thousand yd. shoot a couple years ago, somebody wanted to know what the size of the tgt. was. We actually calcd. it to an accuracy level of .3" using a mil-dot reticle at a power other than calibrated by measuring it on a known size tgt. at 500 yds. Basically we reverse-milled the subtension, then reverse-milled the tgt. size. Did that at another shoot this last year that the lasers wouldn't bounce off of, and it also worked. Pretty amazing what can be accomplished with this stuff sometimes. Takes just the right sort though--a shooter that has a bit more than a passing interest in mathematics.
