[QUOTE="Michael Eichele, post: 30121, member: 1007"] rescurat, I am not sure if this would help, but if it does here it is. An example for calculating wind would be like this: 3000 (range in feet) divided by muzzle velocity(2600)=1.1538 The real time of flight for standard air density would be (at 1000 yards) 1.7651 useing a 168 grain .308 caliber bullet. Then, 10 miles per hour times inches per second (10x17.6)=176.0 Next take the real time of flight and subtract the time of flight as if there was no apmoshere (1.7651-1.1538)=0.6113 This is the delay time, now multiply the delay time by the inches per second (.6113x176)=107.58 inches at 1000 yards [/QUOTE]
