The most fun you can have with a shotgun.
SKEET AND TRAPSHOOTING by Jerry Pardue
Originally designed to provide practice for field shooting, skeet and trap are now sports in
themselves.
Trapshooting was first mentioned in 1793 in an old English magazine, "Sporting Magazine."
For many years, in Europe and America, live birds were used as targets, being released from
under top hats by jerking the hats off with a string. These shooters were known as the "High
Hats Club." Later, boxes were used much the same as top hats.
Toward the end of the nineteenth century public sentiment caused legislation to prevent live
bird shoots. Over several years a progression of man-made targets was used. Many variations
of glass balls, some filled with feathers, were tried. In 1880, a fat clay bird was used. With
little change, this type target is still used today.
Cincinnati had trapshooting in 1831. In June 1900, 74 contestants competed in the first Grand
American Handicap Trap Shoot. Since that year, the Grand American has become the largest
trap shoot in the world. Every trapshooter wants to attend and win at the Grand. In 1996,
approximately 5,000 shooters of all ages competed in the Grand American Handicap,
shooting at 100 targets each during one day of shooting. The Grand lasts for some ten days.
The Interstate Trap Shooting Association, formed in 1890, organized and regulated the sport
in the United States until 1922. The present Amateur Trapshooting Association (ATA)
evolved from these beginnings in 1923. The ATA is headquartered in Vandalia, Ohio, where
the Grand American Handicap is held each year. The membership of the ATA in 1977 was
more than 48,000.
Skeet shooting is a way of life-exercise for the body, mind, and soul for more than 50,000
members of the National Skeet Shooting Association. Through winter and summer they shoot
at millions of targets-breaking most of them-meet new people, and travel across the United
States.
It all started on the grounds of the Glen Rock Kennels in the town of Andover,
Massachusetts, in 1920. It was there and then that a small group of upland game hunters,
including the late C.E. Davies, proprietor of the Glen Rock Kennels, his son Henry W., and
the Late William H. Foster, all of Andover, were shooting at clay targets as a means of
obtaining wing-shooting practice with their favorite upland guns. Their shooting gradually
developed into a regular program that gave each shooter the same series of shots so that the
competition, which was inevitable, might be even.
Originally, the arrangement was a complete circle with a twenty-five-yard radius with the
circumference marked off like the face of a clock. The trap was set at "12 o'clock" and was
set to throw the targets over "6 o'clock." The competitive program consisted of shooting two
shots from each of the twelve stations. The shell that was left over from a box was used, first
as a stunt, to shoot at an incomer from the center of the circle. This later proved to be a shot
offering real snap-shooting practice and has since developed into the plan of station 8 shots of
the regulation skeet program.
"Shooting around the clock," as it was informally called, had most of the elements of modern
skeet shooting. But a commonplace incident then occurred that had a distinct bearing on the
present day program. In "shooting around the clock," shots were fired to all points of the
compass, until a neighbor started a chicken farm in a lot adjoining the kennels. That put a
stop to shooting in that direction. Foster solved the problem by producing a second trap and
placing it at "6 o'clock" so it would throw its target over "twelve o'clock." This gave the
shooter the same problems as were found in the original clockface, but reduced the danger
area by half.
Noting the appeal of this form of shooting, Foster became convinced that development of the
idea could be made nationally acceptable. He therefore set about to complete a shooting
program that would contain all the necessary elements of wing-shooting practice and of a
competitive sport. Among the additions were the four sets of doubles and the optional shot.
When details of the sport had been worked out and tested and a set of rules had been drawn
up, the idea was introduced to the public in the February 1926 issues of both National
Sportsman and Hunting and Fishing magazines. At the same time, a prize of $100 was
offered for the most appropriate name for the new sport. It was won by Mrs. Gertrude
Hurlbutt of Dayton, Montana, who suggested "Skeet," an old Scandinavian form of the word
"Shoot." Some 10,000 entries were received in the contest.
The American shooter was apparently ready and waiting for a practical form of wing
shooting with the shotgun that would give him an opportunity to test his skill any month of
the year on a series of shots similar to those encountered in hunting and, as evidenced by the
popularity of skeet shooting today, it has far exceeded the expectations of its sponsors.
As the popularity of the sport grew, the forming of a national skeet shooting association was
inevitable. This came about and the first National Championship Shoot was held August 16-
31, 1935, at Cleveland, Ohio. The 12 gauge (then called the all gauge) entry in that shoot
totaled 113 participants. This tournament became an annual fixture, being rotated around the
country, and the last championship under the original association was held at Syracuse in
1942. Skeet then became non-existent during World War II as far as civilian shooters were
concerned. Equipment and ammunition became unavailable. Most of the participants had
gone to war. Gun clubs ceased to operate and many disappeared completely. However, the
government quickly recognized the value of the sport in gunnery training, and all branches of
the armed forces relied on skeet to teach servicemen the principle of loading moving targets.
Many of the great civilian shooters rushed into the service and most of them were used as
instructors.
With the end of the world conflict, a dedicated group of skeet enthusiasts officially brought
the sport back to the public with organization and incorporation of the present National Skeet
Shooting association in December, 1946. This new association was financed in the beginning
by a substantial, nointerest loan from the National Rifle Association. The National
Championship Shoot was resumed at Indianapolis in 1946. The home of the NSSA is now in
San Antonio, Texas where the National Matches and other large matches are held.
In addition to the regular skeet shooting program of 12, 20, 28 gauge and .410 bore
competition, there are the international style and collegiate divisions, both with specifically
designed regulations. The international style features the previous low-gun position and
variable-timing target release required by NSSA rules up to 1952 Contrasted to the present
cheeked gun position, this style is required by the international shooting union, a worldwide
shooting organization, and the international olympic committee, producer of the Olympic
games, where skeet shooting was first included on the program in 1968.
The Trap and Skeet Shooting courses at Tennessee Tech are offered to present these sports to
the beginner and, if interested, carry this person into the advanced stages of competition on a
local, state, national, and/or international level.
BEGINNING TRAP AND SKEET
This course is to introduce the student to the safe handling of shotguns, range procedures and
basic rules of each sport, reloading ammunition, and shooting both trap and skeet.
The activity fee for the course covers all materials necessary for the class guns, ammunition,
reloading components, targets, range, and instruction.
This class meets for one two-hour session each week. The first class meets in a classroom at
Tennessee Tech as published in the semister bulletin. All other class meetings will take place
at Bend of the River Recreation Area. This is located 10 miles north of Cookeville on
Highway 136 (North Washington Avenue.
Handouts will include: a list of terms, definitions, and rules which each student should be
familiar with; sample score sheet showing how to score both trap and skeet; list of ATA
rules; diagram of trap range; diagram of skeet range; parts of cartridge.
Grading for this course is not based on proficiency at shooting. Although we hope each
student has good scores, there is no reasonable, fair way to use scores on the range for your
course grade. Three written examinations and participation will be used to determine the
letter grade for the course.
TRAP
In trap, the shooting is done from five adjacent positions in a crescent-shaped formation 16 or
more yards behind the "trap." Shooting is done in rotation with the person in number one
position firing first and so on. Each person fires at an individual target. After each has fired
five shots from a particular position on the crescent, all move one station to the right until
everyone on the squad has fired from all five positions for a total of 25 shots. The trap squad
consists of five people or less.
The "trap" is concealed in a low house in front of the shooting stations. Clay targets are
thrown from the house at various angles unknown to the shooter. The targets are thrown away
from the "trap" 48-52 yards and in any direction within a radius of 44 degrees. The arc is
centered on the "trap" and station 3.
As in skeet, the objective in trap shooting is the breaking of a fast moving clay target. The
targets used in trap are the same as those used in skeet. Beyond these factors, however, the
two sports are markedly different.
Unlike skeet, trap contains an element of the unpredictable. Because the shooter can never
guess which angle the target will follow, it is impossible to use a cut and dried formula in
determining proper leads. The principles of lead, swing, and follow-through are applicable to
all forms of shotgun shooting. In trap, just as in skeet, no follow-through after firing is certain
to cause a miss. Good stance and proper gun mounting are equally essential to the
trapshooter.
Most trap targets are rising as well as going away from the shooter. Therefore, they require an
upward lead in addition to whatever quartering lead may be indicated Remember to establish
proper horizontal and vertical lead and continue your swing and follow-through as you fire.
As the new shooter gains experience through practice, he will gradually acquire a conditioned
memory image or mental picture, of how far over, right or left to lead every target thrown. It
will take time, but eventually, each memory image, neatly tucked away and classified in the
mind, will come flashing through with computer speed to match every target angle
encountered. Trite but true, practice makes perfect.
COMPETITION TRAP AND SKEET
By this time the student should have a fairly good grasp of the basics of shooting trap and
skeet. This course is directed toward getting the student involved in actual competition. The
class meets for a one-hour session each week on campus. Shooting times are arranged by the
student. One requirement of the course is to attend and participate in at least one registered
target competition sometime during the quarter. These are held year-round almost every
weekend and transportation is usually easy to obtain.
SHOTGUN INFORMATION
Gauge
The gauge of any shotgun is determined by the inside bore diameter of the barrel. The largest
gauge allowed in modern hunting is the 10 gauge. However, the 12 gauge has attained the
greatest popularity of all gauges, because of its versatility. It is capable of providing loads
nearly equal to 10 gauge, and, of course, recoil is noticeably less. The 16 is a close
competitor to the 12 in versatility and has many advocates who will use nothing else. It is an
excellent gauge for upland game, and very effective for practically all waterfowl shooting.
Most enthusiastic shotgunners seldom go long without a compact little 20 gauge. The
"Twenty" has extremely fast handling and pointing characteristics which make it delightful
for both the novice and skilled shooter. Improved loads have now made the 20 gauge most
suitable for varied types of shooting.
The 28 and .410 gauges also feature exceptional handling ease. However, these two gauges
carry some 25 percent fewer pellets than the normal 20 gauge load, and are therefore used
primarily by the skilled upland bird hunter or skeet shooter capable of picking up the target at
close range.
Every gauge listed has features desirable for specific types of shooting, as well as for specific
types of shooters. But, the desire for lighter weight and lighter recoil need not limit a shooter
to one gauge. Browning now provides light weight and light recoil in every gauge it makes.
This, combined with proper shell selection, can assure pleasant shooting in any gauge. Just
select the Browning gun and gauge you like best.
Choke
Choke refers to the amount of constriction in the bore of the shotgun barrel. This choke
commences about three inches from the muzzle so that the inside diameter of the barrel at this
point is less than at any other point along the tube toward the breech. This constriction
slightly squeezes the shot charge mass just before it leaves the gun, tending to keep the shot
charge pellets from spreading wildly. The more the constriction, within known limits, the
tighter will be the concentration of shot in flight at any given distance.
A cylinder bore has no choke at all. With no constriction in the barrel at any point, the shot
flares toward the target in a broad and loosely held mass. At the other extreme is the full
choke gun which provides the maximum concentration of shot in flight.
The degree of choke is custornarily measured by the percentage of pellets which hit within a
30-inch circle at 40 yards. In the same gun this percentage may vary slightly, depending on
the size of shot, velocity of shot, and amount of shot used. But on the average, the following
percentages may be expected in Browning barrels with wide variety of loads available.
Comparable percentages may be expected from the 28 gauge and the .410 gauge at about 35
yards.
Average Browning Percentages Identification 30 Inch Circle
Choke on Barrels at 40 Yards
Full * 65-75%
Improved Modified o- 55-65%
Modified *- 45~55%
Improved Cylinder ** 35-45%
Skeet **S 30-35%
Cylinder *** 25-35%
The degree of choke is often referred to as pattern percentage, or pattern, although pattern
includes a slightly broader meaning. Even more important than the percentage of pellets
hitting within the prescribed area is the even distribution of the pellets in that area. Within the
range for which any particular choke is engineered, the pattern should have no holes as large
as the target. For example, it has been determined that five hits of number 5 shot are
generally required to kill a duck. Therefore, at the effective range of the gun and cartidge, the
pattern should be tight enough that at least five number 6 shots are within the area of a duck's
body at any point in the pattern circle.
The choice of choke should be made in relation to the distance at which most targets are to be
shot. If the game is generally shot at distances of 40 yards or more, then a tight choke
(improved modified or full) is appropriate. A modified choke would give approximately the
same pattern density at 35 to 40 yards, improved cylinder 30-35 yards, and so on. Since
studies have shown that the great majority of game is shot at ranges under 40 yards, the
modified choke is the most generally accepted for all-around shooting conditions.
Barrel Length
It is still assumed by many that the longer the shotgun barrel the farther the gun will shoot,
the more effectively it will perform, and the more closely it will pattern.
The facts are, however, whatever the gauge, barrel length has small effect on the velocity of
the shot charge. With modern powders, the shot charge reaches maximum velocity after it has
traveled a relatively short distance up the barrel bore. (Longer length of barrel does not make
the pellets move faster or go farther.) Since the degree of choke controls the pattern of the
shot at the target the proper barrel length is entirely a matter of desired weight, balance, and
sight radius.
Barrel Length
It is still assumed by many that the longer the shotgun barrel the farther the gun will shoot,
the more effectively it will perform, and the more closely it will pattern.
The facts are, however, whatever the gauge, barrel length has small effect on the velocity of
the shot charge. With modern powders, the shot charge reaches maximum velocity after it has
traveled a relatively short distance up the barrel bore. (Longer length of barrel does not make
the pellets move faster or go farther.) Since the degree of choke controls the pattern of the
shot at the target the proper barrel length is entirely a matter of desired weight, balance, and
sight radius. The longer 30 or 32 inch barrels add weight at the muzzle for steadiness, and
provide a longer sighting plane for the slower, more deliberate swing required to hit more
distant targets. The shorter barrels are preferred whenever quickness in getting a gun
shouldered, and general ease of maneuverability, are important.
The size of the individual is also a consideration. A small person will likely be more accurate,
even for distant targets, with a shorter barrel since the longer barrel may be uncomfortably
heavy and slow.
Rib
A rib on the top of the barrel rapidly channels the eye down an uninterrupted sighting plane.
A ventilated rib also minimizes heat wave distortion that occurs down the sighting plane
when the gun is fired in rapid succession.
Gun Stocks
There are three specific measurements important in any shotgun stock. The measurements, as
illustrated below,* are "drop at the comb," "drop at the heel," and "length of pull."
Since exhaustive research and experimentation have shown that these three measurements
can greatly affect shotgun shooting success, Browning Arms Company takes special care to
meet the most desirable measurements in each stock produced.
A stock that is too long may catch under the arm pit or drag on the lower shoulder. It will feel
uncomfortable and awkward, and can markedly delay the fast execution of a shot. On the
other hand, the stock that is too short will cause more kick to the shoulder, and hurt the
shooter's face as well.
Since shotguns have no rear sights as do rifles, the shotgunner sights along a plane from
breech to barrel muzzle to target. In effect, the shooter's eye is the rear sight. Thus the amount
of drop at the comb is extremely important in its effect on good or poor shooting. Should the
comb be too low, the shooter's eye will be too low when the gun is properly cheeked, and the
gun will throw the charge below the mark. If the comb stands too high, the impact of the
charge will consistently be above the target. In addition, the
shooter must place his cheek against the comb of the stock at the same spot and in the same
manner on each successive shot. Otherwise, the shooter will be erratic, sometimes shooting
under his target and sometimes over.
The drop at the heel measurement is just as important to good shooting as is drop at the
comb. It contributes a great deal to proper gun alignment, and if excessive, will cause the
recoil to be more noticeable. A 15/8 inch drop at the comb, a 21/2 inch drop at the heel will
prove correct for at least 95% of the shooters.
For trap and skeet guns it will be observed a straighter stock is provided which means less
drop at both the comb and heel. This is because the target is small and generally shot on its
rising trajectory. With a straighter stock there is less danger of shooting under the bird -even
though the shooter holds dead on without blotting out the bird with the muzzle as the shot is
fired.
The shooter of average physical characteristics should use a stock of standard dimensions.
The drop at both comb and heel will generally fit well. Any minor adjustment in the length of
the stock should come after some shooting has been done.
The Proper Gun
The shotgun you buy should have the characteristics best suited to your physical build and
type of shooting you intend to do. In this article is a chart to help the new shooter determine
best gauges, etc., for various game. The "Proper Gun" is, of course, a debatable subject since
what is best for one shooter, or one species, might not be for another. The recommendations
are presented to help the new shooter determine the best gun for him under various
circumstances.
Extra Barrels or Variable Choke
By referring to the chart it will be noted that the same gun can be used on various game under
varying conditions by changing from one barrel to another of different choke and length. On
all Browning automatic shotguns, barrels of the same gauge and model are readily
interchangeable. Thus a duck gun can become a skeet gun, or a fine upland game gun, by
changing barrels.
Versatility of a gun can also be increased by having one of the several good variable choke
devices installed on the end of the barrel. Such a device permits the shooter to switch from
one choke to another as shooting conditions require. The resulting patterns, although possibly
not quite as good, approximate the desired choke for most purposes. However, one should
expect the balance of his gun to be slightly upset because of the added weight of the choking
device. It is popular today to use screw in chokes. By simply changing the tube at the end of
the barrel , you can carry all the different chokes in one pocket.
SHOTGUNNING HINTS
The suggestions listed below are primarily for the novice hunter. The experienced gun man
has already put them into practice. The fundamentals are: correct gun position, proper
shooting stance, effective range, and swing.
Correct Gun Position
Place the cheek firmly against the stock in a position that enables you to see the target clearly
over the end of the gun. Do not sight down the barrel as in rifle shooting. This causes you to
shoot low, and interferes with an unobstructed view of the target in flight.
Keep the head down. Misses are often caused by cheeking the stock, then raising your head to
look for the target. Remember that in shotgun shooting, your eye acts as the rear sight. Once
on the stock, your cheek should remain there.
Proper Shooting Stance
Face the target. A right-handed shooter should, if possible, point his left foot toward the spot
he intends to fire. This will prevent body cramping. Feet should be spread comfortably apart.
Lean forward slightly, with the forward knee bent slightly, weight on the forward foot. On
angle shots, pivot from the waist. Always keep the gun in motion even after shooting.
Follow-through pays off!
Effective Range
Know the range of your gun. Shooting when game is beyond range is a major cause of
crippling and loss of game. The type of choke in your gun determines maximum effective
range. If you are unsure, pattern-check your gun on large sheets of paper at various ranges.
Then hold a decoy, or other gamesized object, against the pellet pattern. This
will show you at what point the shot charge becomes too spotty for effective hits. Compare
rocks or other objects that approximate size of the game you will be hunting at various
distances. With a little practice you will be able to determine distance almost instantly.
Lead, Swing, Follow-through
When shooting at moving game, especially faster waterfowl in full flight, it is necessary to
shoot well ahead of the bird. It would be impossible to make an accurate chart covering all
the variables of the bird's speed, distance from shooter, and angle of flight. In addition, a bird
can move 5 to 20 feet in the time a hunter can pull the trigger. Only by swinging through the
target, determining what appears to be the right amount of lead, and following through after
the shot is fired, can consistent success be attained. It has been said that 95 per cent of all
misses occur because the shooter stopped the gun when he pulled the trigger.
THE SHOTGUN SHELL
A box of shotgun shells usually lists five specif ications:
Gauge-usually printed as 12 Ga., 16 Ga., 20 Ga., etc.
Length of shell-printed as 2 3/4", 3", etc.
Drams equivalent- printed as 3 1/4/. Drams equiv.
Size of shot-printed as 2, 4, 6, etc.
Ounce of shot-printed as 1 1/8 OZ., etc.
Gauge
It is vitally important to pay particular heed to the possibility of mixing up shells of different
gauges. Persons who hunt together with guns of different gauges, as well as the man who
owns different gauge guns, should keep shells carefully separate and constantly recheck
before entering the field. For example, a 20 gauge shell will slip into a 12 gauge barrel so its
rim rests on the forward edge of the forcing cone of the chamber. The shell will not fire and
cannot be readily seen. If a preoccupied hunter mistakes failure to fire as a failure to load, he
may add a 12 gauge shell into the chamber. The 12 gauge shell will slide into the chamber
behind the 20 gauge so smoothly the shooter is completely unaware. Upon firing, the
obstruction caused by the 20 gauge shell can cause serious injury.
Length of Shell
All shotgun barrels are chambered to accept shells of specific length. If shorter ones than
designated are used, there is no danger. But if a longer shell is chambered, it may result in a
dangerous constriction of the shot charge and gas wads as they pass through the forcing cone
of the chamber.
The shooter should aiso realize that the size designated on the gun barrel means the length
after firing. While a shell marked 2 3/4" may actually measure 2 1/2" with the edges crimped,
firing will open them up. That is the length shell the gun must be able to handle.
The owner of a shotgun can use shorter shells, with excellent pattern performance, if a
heavier load is not required to do the job. But never load a longer shell into any gun than that
which the gun is designed to shoot.
Dram Equivalent
Today's modern smokeless powders produce far greater power, with much less weight, than
the old black powders. The black powder shells were measured in drams (1/16th of an ounce)
while the smokeless powder shells are designated in drams equivalent. Thus a shotgun shell
marked "3 1 /4 dram equiv." contains enough smokeless powder to produce the same power
produced by 3 1/4. drams of black powder.
Shotgun powder burns more quickly than rifle powder. With the relatively large bore required
by a shotgun, it would be heavy and burdensome if thick barrel walls were used througho ut,
as with rifle barrels. Therefore, shotgun shell powders are made to burn more quickly,
exerting the greatest energy near the thicker-walled breech. Obviously, shotgun shell
handloaders should always take every precaution to use none but the prescribed powders.
Size of Shot
Lower numbered shot, such as 2 and 4, provide the maximum distance and killing power to
be used on fox, turkey, geese, and similar game. The higher numbered (and smaller sized)
shot such as 6 or 7 1/2, is preferred by most hunters for pheasant. Size 7 1/2 or 8 shot is good
for smaller upland game, such as chukar partridge and bobwhite quail, and in trap. Most skeet
shooters want more pellets, and therefore use 9s.
Ounces of Shot
The greater the distance from muzzle to target, the wider the shot pattern. Therefore, more
pellets are needed for greater pattern density in longer range shooting. Check the chart to see
the various ounces available, and the recommended ounces for each species of game. Heavier
loads will be required for shooting beyond 45-50 yards. Lighter loads are required to avoid
mutilating smaller game at close ranges. Most hunters purchase the heavier loads only when
specifically required, since expense is greater.
TRAP SHOOTING ETIQUETTE
1. Make your entry far enough in advance so that the office can properly process it. Clubs
want shoots to start on time, but they can't if shooters don't sign up enough in advance so that
squadding and record keeping can be done.
2. Be ready when your squad is called and also when it is your turn to shoot in the squad.
3. Do not lean over each time to pick a shell out of a box on the ground or to pick up empties.
Have your shells where you don't have to stoop to get them.
4. Do not raise your gun until the shooter ahead of you fires.
5. Remain at your post until the fifth man has fired, then move to the next position. At the end
of the round, stand facing the traps until the last man has fired the last shot. If you are leadoff,
do not fire until all squad members are in position after each change.
6. Never load your gun before changing positions. When going from position five to position
one, turn to the right to avoid bumping guns with the man coming from post four.
7. Load only one shell at a time, except in doubles. Close the gun only when it is your turn to
shoot. If a delay occurs, remove the shell.
8. Do not allow ejected shells from your gun to hit or annoy other shooters.
9. Do no unnecessary talking when you are on the firing line. When you are not on the firing
line, keep your voice down when you are around other squads which are shooting.
10. Time your shooting to establish rhythm in the squad. Call in a loud clear voice so that
there is no confusion about when the puller should respond.
11. Be a sportsman at all times. Be sure your competitors get what is due them, but do not be
a target claimer.
12. Observe safety rules. Do not point your gun at another, even if it is unloaded. On the
firing line, always keep your gun pointed toward the ground or the traphouse.
13. Shooters are always willing to have you look at their guns, if you ask permission first. Do
not pick up another's gun from the gun rack and handle it without asking.

some angle between and including a straightaway from station 1 and a straightaway from
station 5.
Irregular target-An unbroken target that does not conform to a regular target. Under no
circumstance shall the results of firing upon a broken target be scored.
Regular double-In doubles, the recommended method of throwing targets shall be such that a
regular right hand target be an approximate straightaway from station 1 and the left hand
regular target be an approximate straightaway from station 5. However, no target shall be
declared irregular unless it varies more than 25 degrees from these angles.
Irregular double- Either or both targets thrown as irregular targets.
Balk-Failure to shoot at a regular target.
Malfunction of gun-Failure of the gun to function, or work, as it was designed to do, not
failure of a shell itself. Malfunction of a gun applies only to a second shot of doubles.
Misfire-Failure of a shell to fire when the primer is struck with the firing pin or when
evidence is present that the hammer did fall even though the primer shows no indention.
Dud shell-A shell which lacks a live primer or one in which the primer fires but through
failure of the shell or lack of components and which consequently leaves part or all of the
charge of shot or wad in the gun. A soft load in which the shot and wad leave the gun barrel
is not a dud.
"Dead target"-A regular target that has at least a visible piece broken from it or is completely
reduced to dust as a result of being fired upon by the shooter. A dusted target (a target from
which there is a puff of dust) but no perceptible piece, is not a broken target.
"Lost target"-A regular target from which in the sole judgment of the referee no visible piece
is broken after being called for by the shooter.
There is no optional shot in trap.
Trap squad-A trap squad is normally 5 members. It may be less but never more.
Round of trap-A trap round is 25 shots taken 5 at each of 5 stations. For singles and handicap
and a pre-announced number of pairs at each station for doubles.
Scoring-The score in any one round shall be the number of dead targets. A "O" shall be used
to designate a lost target and an "X" shall be used to designate a dead target..
Handicap shooting-ATA Handicap system handicaps the shooter by distance from the trap
house. Theoretically, shooters' abilities should be reflected in the distance at which they
stand. The minimum is 19 yards while the maximum is 27 yards.
Guns and loads-Guns shall be 12 gauge or smaller but no consideration shall be given to the
smaller guns. The load shall be no heavier than 3 drams equivalent of powder or 1 1/8 ounces
of shot, and a shot size of 7 1/2 or smaller.
