An easy rule to remember the windage correction by is:  “A change of 1 point of wind changes the point of impact 4 inches for every 100 yards of range.”

Copy this table and take it to the range with you.

Example of sight adjustment:  Suppose you are firing at 500 yards.  The first two or three shots show you that your shots are hitting about a foot below and a foot to the right of the center of the bull’s-eye.  From the above table you will see that if you will raise your sight 50 yards and move the wind gauge half a point to the left the rifle will be sighted so that if you aim correctly the bullets will hit well inside the bull’s eye.

SECTION 4.  AIMING.

OPEN SIGHT:  Always align your sights with the front sight squarely in the middle of the “U” or notch of the rear sight, and the top of the front sight even with the upper corners of the “U.”  (See fig. 1.) All the sights on the rifle except the peep sight are open sights.

PEEP SIGHT:  Always center the tip of the front sight in the center of the peephole when aiming with this sight. (See fig. 2.)

[Illustration:  FIGURE 1.]

Always aim below the bull’s-eye.  Never let your front sight appear to touch the bull’s-eye in aiming.  Try to see the same amount of white target between the top of the front sight and the bottom of the bull’s-eye each time.  The eye must be focused on the bull’s-eye or mark and not on the front or rear sight.

Look at figures 1 and 2 until your eye retains the memory of them, then try to duplicate the picture every time you aim.  Aim consistently, always the same.  Never change your aim; change your sight adjustment if your shots are not hitting in the right place.

SECTION 5.  BATTLE SIGHT.

The battle sight is the open sight seen when the leaf is laid flat.  It is adjusted for a range of 547 yards.  It is intended to be used in battle, when you get nearer to the enemy than 600 yards.  Always aim at the belt of a standing enemy, or just below him if he is kneeling, sitting, or lying.  On the target range this sight is used for rapid fire.  With it the rifle shoots about 2 feet high at ranges between 200 and 400 yards, so you must aim below the figure on the target “D.”  Find out in four instruction practice just how much you must aim below to hit the figure.
