But if you look at the magnitude of the drift from 0 to 300 vs the magnitude from 700 to 1,000--it looks roughly three times as much at the distant third??
Missed this earlier.

The bullet is moving slower during the 700-1,000 yd phase of its flight, so for a given amount of sideways acceleration, you will get more sideways motion relative to forward motion than if you impart that same acceleration earlier in the flight where the bullet is moving downrange faster.

Also, the bullet is spending longer in that region since its moving slower and therefore the wind has more time to act on the bullet.

It's a combination of both of those things.
