Way back when I had a scope rigged to fit an M2.
My impression it was more artillery than sniping.

"A little"
With that much drop you'd think there be a lot of potential for left/right drift as well. Must be many misses for any 1 hit with those distances.
Windage is not much of a factor with the big heavy 50 cal bullet.
Windage can drive you nuts with 17Rem or .222 Rem or 22/250.
This fades away with the 30 cals but nearly disappears with the .50 cal at practical distances for practical purposes. At 400m even holdover is less a factor for trajectory than the difference between the bore and the line of sight with a 50 cal.
The Soviet 120mm tank gun allows for NO aim-off out to 2 km. That's flat.
Extreme ranges like 2.5km are another matter. Even 155mm experiences windrift out that far.
It was not for naught that a 50Cal coax loaded with tracer was a popular sighting mechanism for western tanks mounting the L7 Vickers 105 mm. They are more or less ballistically identical.
