[QUOTE="Shawn Carlock, post: 191086, member: 4"] It occured to me to deal with the SD as a wind function while doing the testing for NF. I was pouring over the SD results at known ranges and looking at predictability. It occured to me that plugging in the correct wind speed will closely mirror SD and change appropriately with atmosphericial changes. From my data and testing it is not perfect but within an 1" or so at most distances out to 1500+. I based my speed number on hard data from 1000 yards and validated it out to 1500 and some change. I'd like to work the method over at 2000 but have little opportunity for that distance and testing conditions. Hope this helped. [/QUOTE]
