the wind has greater effect on the bullet.
IS this correct cause i though i read some where that the wind closes to the target has the most effect because of the loss of speed. I know i have sure missed a few target on this game because i looked at the wind at the target not at my position.
Please give me some pointers because playing this game is one thing to keep you sharp with calculation but in real life i do not want to miss because i did not know.
Shooting extremely long ranges creates much more challenge, because while the wind is typically homogeneous when shooting short range, it can be from several different directions over the course of the bullet's flight if distances are long enough.
As posted by jerrschmitt, wind "at the muzzle" (which is really wind "during the first portion of flight") has the greatest angular dispersion effect and is usually considered to be the most influential.
Wind downrange also has substantial effect, due to the duration of exposure during the mid-range portion of flight, and also due to the reduced bullet velocity during the final portion of flight.
Most long range target shooters will want to know what the mid-range wind is doing, as well as what the wind is doing at the firing point.
Whenever possible, I will consider wind at the firing point, mid-range wind, and wind near the target. I think of it as wind during the first 25% of flight, the next 50% of flight, and the final 25% of flight, vs wind "at" the muzzle, wind "at" mid range" and wind "at" the target.
If we have no wind data downrange, we only have part of the story, and it pays to learn the indicators that allow us to judge downrange wind speeds.
