1385. Object and importance. After the soldier has been thoroughly instructed in sighting, and in the position, aiming, deflection, and elevation correction drills, he is exercised in firing at short ranges (50 and 75 feet) with the gallery practice rifle (.22 caliber).
Notwithstanding the value of the position and aiming drills, it is impossible to keep up the soldier's interest if these exercises are unduly prolonged. By gallery practice, however, the interest is easily maintained and further progress, especially in teaching the trigger squeeze, is made. Many of the external influences, which on the range affect the firing, being absent, the soldier is not puzzled by results for which, at this stage of his education, he could not account were he advanced to firing with full charges. Furthermore, as there is no recoil to induce nervousness or flinching, the soldier soon finds that he can make good scores, and this success is the surest stimulus to interest.
Not only to the beginner is gallery practice of value; to the good shot it is a means of keeping, to a certain extent, in practice, and practice in shooting, as much as in anything else, is essential. Since it can be carried on throughout the year, gallery practice is of much value in fixing in the men the habit of aimed fire, than which nothing in his training is of more importance.
RANGE PRACTICE1386. Having completed the gallery practice course, the soldier is then advanced to known-distance firing on the target range where he uses the service rifle, with service ammunition.
This known-distance practice is divided into certain regular courses and special courses.
The regular courses and Special Course A are for troops of the Regular Army.
There is also a special course for the Organized Militia and Volunteers and one for Volunteer recruits.
All the various courses are described in detail in the Small-Arms Firing Manual and anyone having occasion to use any of them should familiarize himself thoroughly therewith.
OTHER INSTRUCTION1387. Use of sling. After the soldier has been drilled in the proper standing, kneeling, sitting, and prone positions in the foregoing exercises, the use of the sling will be taught. Adjustments and their advantages will be taught with the idea of noninterference with quickness and freedom of action. The trigger squeeze exercises will then be continued in the different positions, using the sling.
1388. Description and adjustment. The sling is made up of four parts: the long strap, A, forming the arm loop; the short strap, B; and the two keepers, C and D. At one end of each of the straps there is a metal claw, used for adjusting the straps. At the other end of the short straps there is a metal loop through which the longer strap is passed, thus connecting the two straps.
To adjust the sling for firing, the claw of the short strap is disengaged and reëngaged in the proper holes of the short strap, such adjustment as may be necessary being also made in the long strap (the arm loop).
1389. What the sling does. It does two things: (1) It steadies the rifle, and (2) helps to take up the recoil,—that is, to reduce the "kick."
Its use. There are a number of different methods of using the sling. Experiment with different ones until you find and decide upon the method best suited to you.
The sling should be used in all firing,—combat practice as well as at target practice.
Always adjust the sling so that it will be tight.
Have the arm loop no longer than is necessary to reach the middle of the small of the stock. When on the arm, have the lower end of the arm loop well up near the arm pit, with the keeper well pressed down so as to hold the loop fast.
Note the proper adjustments of the sling for the different firing positions,—that is, standing, sitting, kneeling, and prone, and mark the adjustments on the inside of the arm loop, "St" (standing), "Si" (Sitting), "K" (kneeling), and "P" (prone).
It is sometimes advisable to sew a piece of rope to your shirt sleeve to keep the sling from slipping down.
1390. To put on the sling. 1. Put your left hand in the loop, twisting the sling to the left, A, Fig. 38, and holding the rifle with the right hand as shown in the figure. Twisting the sling to the left causes a flat surface instead of the cutting edge of the sling to rest against the wrist.
2. Extend the arm on through the loop, (Fig. 39), bringing the loop well up near the pit of the arm, grasping the piece with the left hand, and pressing down keeper, A.
3. Place left hand between the sling and piece, (Fig. 40), the hand being pressed well forward toward the upper sling swivel, A. Notice how the back of the hand is resting against the flat of the sling.
4. Come to the position of aim, Fig. 41. Pressure is applied to the sling by pressing forward the left hand, and holding the rifle to the shoulder with the right hand. Remember that whatever pressure you apply must be the same for each shot.

Notice (Figs. 41 and 42) how well forward the left hand is, and how the flat of the sling is resting against the wrist and back of hand. See how the short strap, C, (Fig. 41), of the sling is correctly loose.
The thumb should be held along the stock as shown (A) in Fig. 42.

1391. Designation of winds. Winds are designated as "12 o'clock," "1 o'clock," "2 o'clock," etc., winds, depending on the direction from which they come.
Imagine the firing point to be in the middle of the face of a clock and the target to be at 12 o'clock; 3 o'clock will be on your right, 9 o'clock on your left, 6 o'clock in your rear and 12 in your front.
A wind blowing from your right to your left is called a 3 o'clock wind; one blowing from your rear is called a 6 o'clock wind; one from your front, 12 o'clock wind, etc.
The score-books issued by the Ordnance Department have windage charts that have been carefully worked out and all you have to do is this: Estimate the force of the wind in miles per hour, and determine the direction from which it comes (whether a 9 o'clock wind, a 2 o'clock wind, etc.). Then look at the windage chart and see just how much windage you must take.
The simplest and best rule for the beginner is for him to make his estimate and then ask an experienced shot what windage to use, checking this up with what he found on the windage chart. In this way he soon learns to estimate for himself.
Practice estimating the wind. Ask a man who has been making 5's and 4's what windage he used and check up with your own estimate.
You can find out the direction of the wind by watching smoke, grass or the limbs of trees.
Throw up some small straws and watch which way they are blown, or wet your finger and hold it up. The wind cools the side it strikes.
A 12 o'clock wind slows up the bullet and a 6 o'clock wind helps it along,—so, in the first case you would need more elevation and in the second less elevation.
1392. The zero of a rifle. The twist of the bullet given by the rifling of the barrel causes the bullet to move to right, which movement, called "the drift," is compensated by having the slot in the rear sight for the drift slide, slope to the left. However, in some rifles the compensation is too great and in others it is not enough.
That reading of the wind gauge necessary to overcome the drift of a rifle at a particular range is called the "zero" of that rifle for that range, and all allowances for wind should be calculated from this reading.
The "zero" of a rifle is found by shooting it on a perfectly calm day.
1393. Estimating distance. Ability to estimate distances correctly is an important part of a soldier's education.
While it is true that fire on the battlefield will usually be by groups and the ranges will be given by officers, the battlefield is reached only after a long series of experiences in scouting, patrolling, and outpost duty, in which the soldier is frequently placed in positions where it is necessary that he shall determine for himself the range to be used in order that his fire may be effective.
There are different methods of estimating the range (for example, by sound, trial shots, range-finding instruments, etc.), but the only ones that the average soldier need know are those of estimating distance by the eye and by trial shots.
To estimate distance by the eye with accuracy, it is necessary to be familiar with the appearance, as to length, of a unit of measure which can be compared mentally with the distance which is to be estimated. The most convenient unit of length is 100 yards. To impress upon the soldier the extent of a stretch of 100 yards two posts 100 yards apart, with short stakes between to mark each 25 yards, should be placed near the barracks, or on the drill ground, and the soldier required to pace off the marked distance several times, counting his steps. He will thus learn how many of his steps make 100 yards and will become familiar with the appearance of the whole distance and of its fractional parts.
Next a distance of more than 100 yards will be shown him and he will be required to compare this distance with the 100-yard unit and to estimate it. Having made his estimate, he will be required to verify its accuracy by pacing the distance.
A few minutes each day should be spent in this practice, the soldier often being required to make his estimate by raising his rear-sight leaf and showing it to the instructor. After the first drills the soldier should be required to pace the distance only when the estimate is unusually inaccurate.
The soldier should be taught that, in judging the distance from the enemy, his estimate may be corrected by a careful observation of the clearness with which details of dress, the movements of limbs or of the files in a line may be seen. In order to derive the benefit of this method, the soldier will be required to observe closely all the details noted above in single men or squads of men posted at varying distances, which will be measured and announced.
Although the standing and kneeling silhouettes used in field practice afford good objects upon which to estimate distances, the instructor should make frequent use of living figures and natural objects, as this is the class of targets from which the soldier will be compelled to estimate his range in active service.
