The following are facts and rules taken from the 2010 ATA Rulebook (.pdf). The following mostly concern the shooting range and equipment and I thought they might be interesting to some of our shooters.
Flights and Angles
- Targets should be thrown between 49 and 50 yards.
- Targets should be thrown between 8 and 10 ft higher than station 3, 10 yards in front of the trap house.
- Thrower will throw 17 degrees left and right of center for a total arc of 34 degrees.
- The correct speed of targets for singles trap is minimum of 42 miles per hour measured from station 3 at the 16 yardline. If measuring from in the traphouse the velocity should be a minimum of 44 miles per hour. When using a chronograph the correct speed for singles or handicap is 67 ft./sec.
Targets
- A target shall not measure more than 4 5/16 in in diameter and not more than 1 1/8 in. in height. A target shall also not weigh less than 95 grams or more than 105 grams.
Guns and Ammo
- No guns with a larger chamber than 12 gauge is allowed.
- No loads that contain nickel or coper or tracer loads. The use of lead, steel, bismuth, or other non-toxic shot materials is allowed.
- Loads that are greater than 1290 FPS are not allowed with a shot charge of 1 1/8 ounce. With a 1 ounce shot charge a load may travel 1325 FPS and with a 7/8 ounce shot charge the maximum velocity of the load is 1350 FPS.
- No shell may contain more than 1 1/8 ounces of shot and no shot larger than 7 1/2 is allowed.
