Strong cross winds are an issue as I see it. Winds blowing at you or away from you are not.
I have no data to back me up on this, but if the cross wind is whipping the tree limbs pretty good I try to compensate about 1" towards the wind direction per 15 yards and take only shots that give me a large kill area. About 40 yards is my self imposed limit ... so a 2" - 3" windage is about all I'll ever adjust for.
Now if the wind is in the 30-40 mph range or greater .... I am usually sacking in for the day !!.
