[QUOTE="sscoyote, post: 266108, member: 1133"] I also like to apply reticles for rangefinding. It sounds like what u r going to do is have a BDC reticle installed. If u go here-- [url]www.ottllc.com/specialtypistols/sp20.pdf[/url] and reference Item C) Reticle Rangefinding, it defines the system used for any reticle-rangefinding. For your applications the part on ballistic reticle rangefinding is what u would need. I also like to use the TMR for rangefinding. I use the .2 mil subtensions as the main ranging unit always at the optics highest power, since it gives me an accuracy level for interpolating between stadia of .02 mil (.072 inch per hundred yds.). The smaller the unit of subtension the more accurate reticle-rangefinding is. I like the stuff that Dave has posted here. When i range using a reticle tho i want it to have the highest degree of accuracy (smallest subtension) i can get out of the reticle. IPHY system is great for intuitive ranging, but when i range i divide any unit of subtension i am using into tenths )sometimes i attempt 20ths of a unit interpolatively. So if i have a 16" target and it occupies 1.0 of a 2 IPHY subtension, that's 800 yds.--easy, but suppose the tgt. occupies 0.9 of a 2.0 IPHY unit. That's not any less difficult for me to calculate than a 1.4 mil-reading. I still have to apply the formula. I can't do it in my head, but i still want the most accurate system of reference possible, so i will interpolate to that level of accuracy. 16 x 100 / 2.0 / 0.9 = 889 IPHY, MOA, mil., ballistic reticle...whatever u're using for rangefinding u should still understand the basic angular formula so u can get the MOST out of it.
