Shoot, 20 years ago we had electronic pop-ups at 25,50,100, 200, and 400 mtrs. you had to get 36 out of 40 to score expert. The Drill Sgts. would tell you to fire
in front of the target to kick sand on the target to score
because they were so holey that even if you hit it, the
blasted thing wasn't likely to score a hit. Took his advice and scored 38 out of 40.
