Ah, the wind. A very tricky proposition. The only way to really find out what the wind does, and how to judge it, is to spend LOTS and LOTS and LOTS of time IN the wind SHOOTING at the ranges you will encounter when that big buck stops in front of the crosshairs. Those little charts sure are nice, but are absolutely meaningless to me. I have seen winds that will swirl, then stop, then gust in a totally different direction that you think it would. Swirling winds are tricky, as it can be blowing one way here, but 300-500 yards downrange, where your target is, it can be perfectly calm, or blowing the OPPOSITE direction!
