    Sweetas Rushy your understanding is pretty good. Certainly a logical arguement... but... for arguements sake i'll pose a simple theorectical example

    I shoot a flash bang calibre... that fires a bullet at 3000fps (at the muzzle), when that bullet reaches 1000m it is going only 1500fps.
    I fire my first shot at a 1000m target. There is a 2m/s wind from 9 o'clock between 0m and 100m. This shifts my bullet off path by 2cm at 100m. With no other wind when my bullet gets to the target at 1000m it has drifted 20cm total.
    I fire my second shot at the same 1000m target. There is now a 2m/s wind from 9 o'clock between 900m and 1000m. Ignoring slight variations in the projectiles BC due to its slower velocity because the bullet is going half as fast lets say it drifts twice as much - so 4cm total.

    Yes, yes i know. What about the elevation effect of the wind, coriolis effect, spin drift.... i thought pulling the trigger harder would make the bullet go faster, the cross hairs weren't on the center of the target... that's why i said a simple example. There are some very smart shooters on here though and i'm sure they'll comment on this example
