In that same hour you were looking for a chart you could have figured out the drift by shooting the gun. No chart is going to show you what is happening in any real actual shooting situation anyway. I just spent three days shooting prairie dogs in wind that changed direction several times and varied from 0-20 mph all the time. A well sighted in gun and a good spotter and you can pin it down in a couple shots.
For a chart to mean anything you would need FPS at a given distance, BC of the bullet, speed and direction of the wind (most charts on based on exact wind direction and speed)among other things.
