Yes, it can. With a right hand twist barrel, the bullet will tend to hit low with a left wind and high with a right wind. Not sure why, but I have seen it on target enough to know to correct for it when the wind changes sides.

Yes, really.

Except that distance traveled affects time-of-flight, which gives gravity more time to do its thing.

Don't know how "huge" it would have to be, but we see it all of the time on the target.

Just opinion? That would imply that "science" is omniscient. And there are plenty of facts in this discipline that likely cannot be explained, but after tens of thousands of rounds on target, they also cannot be denied.
