Make the shooter call their shots. After all, you need to know if the shot went left because they pulled it left or because the wind blew it over there. As discussed above, it is up to the spotter to decide whether they believe the shooter. All “good” shots aren’t really good. However, if the shooter says “I don’t know” or they tell the spotter that the shot was bad, the bullet impact can’t be trusted and the spotter should have the shooter shoot again.
