 Section 3. Table of sight corrections. 



236 



Shotcing to ichat extent the point of impact is moved by a 

 change of 25 yards in elevation or 1 point in windage. 



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 

 tire 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: Ahvays center the tip of the front sight in the 

 center of the peephole w^hen aiming with this sight. (See 

 fig. 2.)
