We use to have a guy, when we were shooting score at WWCCA, back about 20 years ago, would walk down to pick up his target, have a .30 cal bullet in his pocket and punch it through a 6mm hole to gain an extra point. When Pete, who was the range conducter at the time, noticed this, he implimeted the range would have a target person to go down and pick up the targets. That guy never showed up again, in actual fact, that guy argue the fact a target person, hired by the range, would go down and pick up his target. He has never shot again in competition, so what do you need rules for?
