Men's Skeet
Competitors move through a semicircular range featuring eight shooting
stations. At each station, single or double targets are thrown at least 65
meters (213 feet) from either the high trap house, which is 3.05 meters (10
feet) above ground level, or the low trap house, which is 1.05 meters (3
feet, 5¼ inches) above ground level. The houses are positioned 36.8
meters (120 feet, 9 inches) apart on either side of the range. Each target
weighs 105 grams (3.7 ounces), measures 11 cm (4¼ inches) in
diameter, is 25-26 mm (just less than one inch) thick and travels up to 55
mph. The competitors must hold their shotguns at hip level until the target
appears and may fire one shot per target. The preliminary round consists
of 125 targets shot in five rounds of 25 over two days. Three rounds are
fired on the first day and two rounds plus the final are shot on the second
day. After the preliminary round, the top six competitors advance to a
25-target final round. The order of finish is based on the combined score
from the preliminary round and the finals.

two shots per target. Each target weighs 105 grams (3.7 ounces),
measures 11 cm (4¼ inches) in diameter and is 25-26 mm (just less than
