This is a courtesy to the shooter, but if the referee fails to do so, the shooter should ask him for the total score. Once a shooter leaves the box, whatever is written in as score becomes official, so verifying the score early on can avoid unnecessary litigation and unseemly fistfights. Often stations have both a score keeper and button pusher drawn from the squad. In other clay target sports the person pushing the button calls the birds. The rules of sporting clays do not touch on this, so the squads are free to work it out among themselves.
Many squads prefer to have the score writer call.
Just make sure that the person who will call the birds is designated ahead of time so that there is no confusion. If a mistake in scoring is made and results in a cross-out or erasure on the score card, the referee should clearly initial the correction. The scoring desk may want to ask him about it later to double check. This session of our Court of Sport is now closed. Go forth and commit sporting clays in the sure and certain knowledge that there actually are some rules.
