[QUOTE="Long Time Long Ranger, post: 382229, member: 505"] Strong head winds or tail winds will cause you to shoot slightly high or low as the bullet travels through air pockets and turbulence. Tail wind will increase velocity slightly more than a headwind will slow it down because of the large base of the bullet vs the sharp point in front resists the air better. The base has more surface to push on. Tailwind you should shoot slightly higher with more velocity, headwind slightly lower with less velocity. Most rifles will shoot 2000-2500 mile per hour so figure a 10 mph wind and depending on the exact shape of the bullet it will not be 10 mph faster or slower and you see how slight it would be. In a perfect vaccum the vector could be calculated quite easily but it would take a lot of testing to figure the effect of each bullet in the wind to get the coefficient to put into the equation to make it accurate..
