1Rifle Marksmanship C Prone Position & Proper Sling Use INSTRUCTION: Prone Position ModelSteps in Using the SlingSteps in Building the Prone PositionShot Technique in Prone7C.1 The Prone Position and Proper Sling UseYour marksmanship instruction should have already covered firing in the supported position as well as firing in the standing position. You are ready to begin with the prone position. Prone is the most stable position because it has the lowest center of gravity, has a large support base and uses a sling to help stabilize the rifle. This means that in order to build a good prone position, you must learn how to properly put on and adjust a sling. Using a sling may seem complicated at first, but if you follow the correct steps in putting it on and adjusting it, you will find that without exception, the sling makes prone position shooting much easier. Every shooter should use the sling in prone.

3Steps in Proper Use of the Sling 1. Hold sling with length adjustment down, arm loop buckle up2. Insert arm in loopSteps in Proper Use of the Sling7C.3 How to Put the Sling OnThe first thing that you must do when getting into the prone position is to put the sling on. The photos show the proper steps for doing that.When using the Daisy sling that is issued with JROTC air rifles, hold the sling so that the arm loop buckle is up and the buckle for adjusting sling length is on the bottom of the sling. Lengthen the sling so that is it as long as possible.Insert your left arm (right handed shooter) in the arm loop.Place the arm loop as high as possible on your arm and tighten the arm loop so that it will stay in position on your arm.Extend the sling, turn the sling swivel one-half turn to the right. Again, before getting into position, make sure the sling is extended to its longest possible length.3. Place arm loop high on arm, tighten4. Attach sling with 1/2 turn to right
4PRONEStep 1:Orient the Body--Lay the mat at a degree angle to the line of fire, attach sling to rifle and lay on the mat7C.4 Prone, Step 1, Orient the BodyStep 1--Orient the Body so It Lies at an Angle to the Target. The first step in getting into the prone position is to prepare the position foundation by orienting the body in relation to the target. To do this lay the shooting mat down at an angle of about degrees to the target. Then kneel on the mat, and with the sling already attached to your arm, attach the sling the the rifle. Remember to twist it one-half turn to the right before attaching the sling to the rifle fore-end. Next, lay down on the mat with your elbows extended.Firing Line
5PRONEStep 2: Fix the location of the left elbow (elbow that supports the rifle)Form an imaginary line from the left hand to the left footPlace the elbow directly under that line7C.5 Prone, Step 2, Locate the ElbowStep 2--Place the Left Elbow under an Imaginary Line Going from the Left Hand to the Left Foot. After orienting the body in relation to the target, the next step in building a shooting position is to place the left elbow in the correct location in relation to the body. As you lie on the mat with your left arm extended out to the rifle fore-arm, try to visualize an imaginary line extending from your left hand through your left shoulder and side, down to your left food. The correct location for your left elbow is directly under this imaginary line.If the elbow is located correctly, you can also think of an imaginary plane cutting though the bent left arm. If the elbow is located correctly, this imaginary plane will be vertical. If the elbow is located so that this plane tips either in or out, the position will be less stable.
6PRONEStep 3: Position the butt-plate UP in the shoulder so the head is erectStep 4: Shift the left hand forward and backward until the sights are pointing at target levelStep 4--After finding correct left hand location, adjust hand stop back to hand7C.6 Prone, Steps 3 and 4The next steps involve adjusting the height of the rifle in relation to the shoulder, head and target.Step 3--Locate the Butt-Plate Up in the Shoulder so the Head is Reasonably Erect. In the prone position, keeping the head up will enhance visual performance and allow the position to be more relaxed and less strained. In prone, the butt-plate can remain in solid contact with the shoulder, but keep it high enough to allow the head and eyes to look straight forward through the sights. With the butt of the rifle in a fixed position, you must next adjust the rifle height so that the sights are raised to the level of the targets.Step 4--Adjust the Rifle Sights Up to Target Level by Shifting the Left Hand Forward or Rearward. The height of the rifle must be adjusted by moving the left hand on the fore-end, not by moving the butt-plate up and down. In this step, adjust the rifle height so that the sights are at target level. At this point, be concerned only with having your rifle sights at target level, not with whether the sights point at your particular target. When you find a left hand location on the fore-arm that raises the sights to target level, adjust the hand-stop on the fore-end so that it rests in the fork of the hand. Mark that location so that you can return the hand-stop to that position each time you fire that rifle.
7PRONEStep 5: Tighten the sling until it fully supports the weight of the rifleStep 6: Using the left elbow as a pivot point, rotate the entire position until the sights point at your target7C.7 Prone, Steps 5 and 6Step 5--Tighten the Sling. With the left and and hand stop in the location on the fore-end that keeps your sights at target level, you can now tighten the sling. Tighten the sling in stages until it is tight enough to support the weight of the rifle and your upper body without any assistance from your arm muscles. All of the weight of the rifle and upper body should rest on the sling. By keeping the sling loose until this point, you were able to develop a prone position where your shoulders were in their natural position.Step 6--Rotate Your Position Until the Sights Point at Your Target. If you built your position correctly, you should have a solid position where the sling does the work of holding up the rifle, with the rifle sights aligned at target level and pointing at somebody’s target, not necessarily your own. Your position should already be exhibiting a quality that we call “natural point of aim” or NPA. This is the point where the position points naturally when everything is relaxed. All you have to do now is rotate the entire position over your elbow until it points naturally at your target. Do this by using your feet to slightly lift your entire body and move it to the right or left while rotating over your left elbow. The left elbow is the pivot point for aligning your position on your target. When your rifle’s sights point naturally at your target, you are ready to start shooting in the prone position.
8Shot Technique in Prone Approach from same direction for each shot, exhale & stop breathing, take up trigger slackRelax left arm, center the front sight movements over the bulls-eye7C.8 Shot Technique in ProneSince the movements of your front sight are smaller in prone, the shot technique is also simpler. If you built your position correctly and are using the sling to support the rifle and upper body properly, you should be able to hold the bull’s-eye within the front sight ring. Proper shot technique here is the same as in standing except that your hold movements will be much smaller. Center your front sight movements over the bull’s-eye as perfectly as you can and smoothly press or squeeze the trigger. Center the movement--squeeze the trigger.Squeeze the trigger while the front sight movements are centered
9Loading Pneumatic Rifles in Prone Take arm out of slingGrasp charging handle with left hand--grasp pistol grip with right handPull rifle to rear with right hand while extending charging lever forward with left hand to fully open charging leverSteps 1-2-3Steps 4-5-67C.9 Loading Pneumatic Air Rifles in ProneIf you shoot with a pneumatic air rifle like the Daisy M853, one additional detail to attend to before starting live firing in prone is to learn how to properly charge the air chamber while remaining in position. The slides above show the preferred method for doing this.To charge the air chamber using this method, it is necessary to take the left arm out of the sling and use it to grasp the charging lever handle. The two hands must then extend away from each other to open the charging level to its fully open position. Pause there for a second to allow a full charge of air to enter the air cylinder and then use the two hands to close the charging handle. Once closed, replace the left hand around the sling and onto the fore-end, load the pellet, close the action and fire.This method of charging the M853 requires some upper body strength and not every Cadet will be able to use this method when they first start air rifle firing in the prone position.4. After pausing, push rifle forward with right hand--push charging handle to rear with left hand5. Wrap arm back around sling and return left hand to its position on the fore-end6. Load pellet and fire
10Alternate Loading Method Take arm out of slingTurn rifle over and support rifle with left hand--use right leg to hold butt of rifle downGrasp charging handle with right hand--lift handle to fully open charging handleSteps 4-5-6Steps 1-2-37C.10 An Alternate Loading MethodIf the method of charging air in a pneumatic air rifle explained in the previous slide is too difficult, an alternate method of charging air in the rifle is shown here.To use this method, you must also take the left hand out of the sling. The rifle must then be rolled over so that the charging handle is facing up. Support the rifle with the left hand by grasping the barrel and fore-end. In this method the right leg may be placed over the toe of the rifle butt to help control the rifle. The right hand then lifts the charging handle to its fully open position where, after a pause, it closes the charging handle. When turning over the rifle to charge air, it is important to support it so that the rear sight does not rest on the floor or shooting mat. Failure to do this can damage the sight.Close charging handle with right hand--use left hand to hold rifle up so sights are not damagedRotate rifle up and return left hand to its position in the slingLoad pellet and fire
11Prone Position:The final step in establishing a good position is to practice live and dry firing in the new positionStability comes from relaxing your arms and letting the sling support your position7C.11 Firing Exercises in ProneAs soon as you have worked out a prone position where the sling fully supports your rifle and upper body and with the sights naturally aligned on your target, you are ready to start firing in prone. Be sure to precede each live fire series with dry firing or aiming exercises. It is not necessary to charge air for dry firing so this allows you to get many extra repetitions of correct shot technique in prone.Getting the highest possible scores comes from doing a good job of stabilizing the rifle so that the hold movements seen in the front sight are small. In your first prone firing, pay attention to relaxing your left arm and upper body as much as possible while you let the sling support your position.
