Actually DesertFox, the standard velocity ammo blows less in the wind than the higher velocity ammo. It doesn't seem logical at first, but if you look at the equation for wind drift, it does make sense. It has also been demonstrated thousands of times by smallbore match shooters.
If you look at the wind drift equation, (no I am not going to put it here.) the factor that is more important than most is the difference between initial and terminal velocity. This number is larger for the higher velocity stuff, because it slows down faster. This is especially true as it goes from being super-sonic to sub-sonic. The standard velocity ammo is already sub-sonic or close to it, so does not spend as much time in a high drag speed range.
Not the best explanation I have seen, but believe me, it is definitely true.
