+1 on JBM
I took a readout of my .308 to my first Sniper Match and made 6/10 hits at 550yards off those charts alone, never having shot the gun past 100 yards before the match. Windage took the other 4 rounds off target. Was a life saver that day! I've since compared real world data to it and confirmed that it is dang close.
If you have an iPhone check out "Ballistic" as it uses the same formulas.
