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.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
