[QUOTE="Mikecr, post: 547865, member: 1521"] I agree in a general sense with this illustration and results of near-vs-far wind. But it can be taken further. Wind drift is not really about TOF, but of T-LAG and drift angles. And that's where the boat scenario is better explained. It's only while the boat is deccelerating (lagging) that drift occurs, and the higher that decceleration the higher the drift angle that is set. It often appears that a very fast bullet drifts less in wind. But this seems otherwise after observing a very heavy(high BC), yet slower bullet, produce less downrange drift. If you took a very low BC bullet/going fast -vs- a very high BC bullet/going slow, both with the same TOF by 1kyd, and both exposed to the same near wind, the high BC bullet would win over the low BC bullet -by 1kyd. This, even though the fast bullet had lower TOF while exposed to near wind. It drifts more because it is deccelerating more. Also both bullets deccelerate the most nearer the muzzle than the target, and that's why the drift angles are influenced most up close -vs- far downrange(where TOF constantly increases). Just sayin [/QUOTE]
