2
THE AIM OF COACHING

  such a degree that he has the confidence and
  ability to shoot consistently and accurately
  under all conditions.

3
FORMS OF SHOOTING

• Grouping
• Application of Fire

4
GROUPING
Grouping is the foundation of all good shooting.
5
A GROUP

• Is a series of shots, not less then three, fired
  at the same aiming mark with the same aim, hold
  and trigger operation.

6

• EVEN WHEN FIRED FROM A VICE

The rifle cannot put all of its shots through the
same hole !
7
THE SHOTS FORM A GROUP
X
The Center of the Group is called the Mean Point
of Impact

FACTORY ACCURACY TEST FOR LA95 RIFLE

• At 30m must group to less than 36 mm.
• Rejected if it groups to 48 mm or more.
• Re-test if over 36m but less than 48mm.

9
FACTORY ACCURACY TEST FOR LA95 RIFLE

• Average group size is worked out-
• Average under 36mm - rifle passes.
• Average over 36mm - rifle fails.
• e.g. First group is 42 mm Second group is 28 mm
  So Average is 35 mm - PASS
• First group is 42 mm Second group is 32
  mm So Average is 37 mm - FAIL

10
THE SIZE OF A GROUP IS DETERMINED BY
A Combination of

• THE RIFLE ...
• THE AMMUNITION ...
• AND THE FIRER

12
But the man makes the largest contribution !
13
The Better Firers

?
Produce the smaller groups
14
AN ABOVE AVERAGE GROUPER WILL ACHIEVE A 100 mm
GROUP AT 100 m
Or a 25 mm Group at 25 m
15
A BELOW AVERAGE GROUPER WILL ACHIEVE A 300 mm
GROUP AT 100 m
Or a 75 mm Group at 25 m
16
THE AVERAGE FIRER WILL ACHIEVE A200 mm GROUP AT
100 m
200 mm
100 mm
300 mm
Or a 50 mm Group at 25 mm
17
But why is it necessary to learn to group as
tightly as possible ?

• Because of the Theory of a Group !

18
The Theory of a Group
A group expands in direct proportion to the
range from which it is fired.
100 m
19
The Theory of a Group
So at 200 m it is TWICE the size it was at 100 m
100 m
20
The Theory of a Group
At 300 m it is 3 TIMES the size.
100 m

A 200 mm Grouper at 100 m
225 mm
Firing at 100 m Should be able to hold the bull
with every shot
24
A 200 mm Grouper at 100 m
225 mm
Firing at 200 m Will only be able to hold the
inner
25
A 300 mm Grouper at 100 m
225 mm
Firing at 300 m Will only be able to hold the
outer
26
COACHING GROUPING

• Advising the firer and teaching him to apply the
  Marksmanship Principles so that he groups tightly
  as possible.

APPLICATION SHOOTS

• Applying the group to the target so that the best
  possible score is achieved.

30
CAREFUL ZEROING
ENSURES A CENTRAL MPI
31
A Proper Zero Ensures
Incorrect Zero
Correct Zero
That with the correct range set and no outside
influences the group will form round the Point
of Aim
32
COACHING APPLICATION

• Outside influences will effect the position of
  the group.
• Wind.
• Light.
• Effects of aiming at longer ranges (i.e. harder
  to aim).
• Zero Errors (? ? ?).

33
COACHING APPLICATION

• Advising and assisting firers to get the best
  score by keeping their group in the correct place
  (i.e.. central).
• Regardless of these outside influences.
• How ?
• By advising the firer and teaching him to
• Read and allow for the wind
• Adjust his sights or POA as required
