At a shotgun range I've been to, they have a duck tower about 150 yards behind the clubhouse. It's surrounded by a fairly thick stand of tall trees, but a couple of the stations result in shooters shot trajectory going through the "hole" in the trees and raining down on the front porch of the clubhouse.
I've been standing there and gotten "hit" -- it actually feels no different than if you through a handful of coarse sand into the air and let it fall on you, actually less since you really only feel a small number of pellets because of dispersion.
Shooters are restricted to target loads of #7.5 shot or smaller, so its very light shot. So light that on their "hard" sporting clays course it's very difficult to hit the distant crossing and away clays in any wind. The #7.5 shot has so little inertia that it just gets blown off target.
Many pheasant hunters I've known have stories about getting hit with shot from people on the other side of a field or road hunting on roads adjacent to the field they were hunting on. It's like coarse sand, and pheasant hunting uses much heavier shot than target shot.
