the shoulder gives to the butt of
the rifle the easiest rest. This will probably be the one in which the
force of the recoil will be least felt.

The soldier should persist in this exercise until he obtains a
position in which he feels no constraint, which will not subject him
to bruises from recoil, and from which the mark appears plainly
through the sights. Having secured such a position, he must not change
it when firing, as a variation in the points of support of the rifle,
the distance of the eye from the rear sight, or the tension of the
hold has a decided effect, especially at the longer ranges, upon the
location of the point struck.

=Important.= The soldier should be encouraged to go through these
exercises frequently at other than drill hours, care being taken that,
in the aiming and trigger-squeeze exercises, he always has some
definite object for a mark.

Deflection and Elevation Correction Drills

(Sight-Setting Drills)

=1383. Sight Correction.= You may find when firing at a target that
the first shot has missed the bull's-eye or figure. Now, one of two
things may be done in order to cause the second shot to hit the
bull's-eye or figure: (1) The point of aim may be changed, or (2) the
sights may be moved and the same point as before aimed at.

In order to do accurate shooting it is necessary to have a
well-defined mark at which to aim; consequently, except for very
slight corrections, the method of moving the sights, involving changes
in elevation and windage, is the one to be used.

=Exercises.= In order to give the soldier practice in making
corrections in elevation and deflection (windage),--that is, in
sight-setting,--proceed as follows:

Take an "A" target and rule it off with red vertical lines to
represent range and black or blue horizontal lines to represent
windage deviations, as in Fig. 33. Tell the men to set their sights
(either peep or open) for 200 yards, no windage. Examine the sights
(assisted by the lieutenants, noncommissioned officers and expert
riflemen).

[Illustration: Fig. 33]

Then say, for example, "You have fired a shot at 200 yards with your
sights set as you now have them. The shot was marked here (pointing to
'P,' Fig. 33). Change your sights so as to move the next shot into the
bull's-eye,--considering that you take the same hold as you did the
last time."

(Note. In this case the sight should be lowered 75 yards and 2 points
of left windage should be taken.
