Re: Formula for shooting in a cross wind..
Some math would include:
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 using a 168 grain .308 caliber bullet @ 2600 FPS. 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 atmosphere (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.
Its very hard to do it this way if you cant determine the real time of flight in the current air density. That is a whole other subject.
Limits are only perceived by what has previously been achieved. Push the limits and good things will happen.
