For the American version of the sport, the clay discs are in diameter, thick, and fly a distance of . The international version of skeet uses a target that is slightly larger in diameter [(110±1) mm vs. 109.54 mm], thinner in cross-section [(25.5±.5) mm vs. 28.58 mm], and has a thicker dome center, making it harder to break. International targets are also thrown a longer distance from similar heights, at over , resulting in higher target speed. The
firearm of choice for this task is usually a high-quality,
double-barreled over and under shotgun with 24- to 32-inch barrels and very open
chokes. Often, shooters will choose an improved cylinder
choke (one with a tighter pattern) or a skeet choke (one with a wider pattern), but this is a matter of preference. Some gun shops refer to this type of shotgun as a skeet gun. Skeet chokes are designed to produce a 30-inch shot pattern at 21 yards. Alternatively, a sporting gun or a trap gun is sometimes used. These have longer barrels (up to 34 inches) and tighter choke. Many shooters of American skeet and other national versions use
semi-automatic shotguns and
break-open over-and-under shotguns. The event is in part meant to simulate the action of bird
hunting. The shooter shoots from seven positions on a semicircle with a radius of , and an eighth position halfway between stations 1 and 7. There are two houses that hold devices known as "traps" that launch the targets, one at each corner of the semicircle. The traps launch the targets to a point above the ground and outside of station 8. One trap launches targets from above the ground ("high" house) and the other launches it from above the ground ("low" house). At stations 1 and 2 the shooter shoots at single targets launched from the high house and then the low house, then shoots a double where the two targets are launched simultaneously but shooting the high house target first. At stations 3, 4, and 5 the shooter shoots at single targets launched from the high house and then the low house. At stations 6 and 7 the shooter shoots at single targets launched from the high house and then the low house, then shoots a double, shooting the low house target first then the high house target. At station 8 the shooter shoots one high target and one low target. The shooter must then re-shoot his first missed target or, if no targets are missed, must shoot his 25th shell at the low house station 8. This 25th shot was once referred to as the shooter's option, as he was able to take it where he preferred. Now, to speed up rounds in competition, the shooter must shoot the low 8 twice for a perfect score. == History ==
