A method for the evaluation of the pattern of shot resulting from a single shotgun round for purposes of optimizing the selection of ammunition type and prediction of shot pattern, and a target for its implementation. The shooter fires a single round at the target. Then a rotating overlay allows the pattern of shot to be evaluated with respect to a center aim point and an overlay axis and kill zone. The overlay is rotated through a series of clockwise, then counterclockwise increments. At each increment, the target is scored with respect to the overlay. The number of shot striking the kill zone for each position of the overlay axis is computed and by observation the shooter can determine the optimal ammunition for use with the weapon and for a given type of game.
