I have shot quite a bit of skeet in the past,including some 100 straights, and have seen a lot more straights shot, and most of the time the target was centered in the pattern, and resulted in a cloud of smoke. I have seen several 500 straight runs also, and the guys that can do that don't depend on single pellet breaks to do the job. The chokes used are normally tighter than skeet, and the targets are centered, or hit more toward the front edge. At skeet, only targets shot at station 1 high house, station 7 low house and station 8 are normally hit on the top or bottom. All other shots are edge on to the target. I have seldom seen a hole through the rim of an unbroken target, most have been bottom to top, and I have seen a lot that were chipped on the top or edge by a pellet that didn't break the target.
In the old days of skeet shooting, pictures showed nets set up in the area where the targets fell to catch the unbroken ones for re-use. That was possible in the days of hand cocked and hand set traps, but the automatic traps are too hard on the targets to reuse those which have been previously thrown.
