[QUOTE="Mikecr, post: 417611, member: 1521"] Ok, I believe I've managed to assemble an incremental drift chart that demonstrates the affects of near wind -vs- far wind. You'll notice that hitting a 10mph wind within 100yds is significant(~1.5moa by 1kyd including 50yd + 100yd drifts), even without further downrange wind. You might also notice that ~1.5moa 1Kyd deviation prints under .5moa at 100yds. How can this be? Because drift is not a linear minute of angle path, but a non-linear curve. Much of that ~1.5moa deviation occured WITHIN the first 100yrds, and therefore does not apply to the full first 100yds. It will apply in the next though... Anyway, I doubt it's perfect, but lend me 30 IQ points and I'll make it so.
