[QUOTE="Jon A, post: 52018, member: 319"] Exactly like RBrowning said. Don't think of a plane as something moving along with a crosswind flowing against it. Think about driving your car down a road...and the road is moving sideways as you drive! Wind drift is kind of like that, but like he said, the time of flight is so short that the bullet won't match the crosswind speed until it's way, way WAY out there. Probably farther than any of us shoot. Time of flight is important, definately. The point I was trying to make was it isn't as important to wind drift as it is to drop. In the prior example, the 180 and the 240 have virtually the same time of flight out to 1550 yds. The 180 drops about 55" less. But it drifts about 60" more in the same crosswind. BTW, my numbers differ from Darryl's because I printed the tables out in haste and by default they were corrected to 4400 ft elevation. [img]images/icons/wink.gif[/img] Things shoot flat up high.
