the target) reflects no useful information. Firing another shot group (without a sight change) could provide more information to determine possible firer error.

Shot groups — about 4 cm. The three shot groups shown in Figure G-9 are about 4 cm (six squares on the target) and indicate firer error.
Firers are checked for a proper steady position, that the eye is focused on the front sight post tip (which is placed at target center for each firing), that the breath is locked during trigger squeeze, and that the trigger squeeze is correct.
More shot groups provide better information from which to direct remedial training. The vertical aiming point may not be the same for each shot since the vertical dispersion is greater than the horizontal dispersion. Any problem with finding target center of mass is probably in the vertical plane and not in the horizontal plane. If the soldier has his eye focused on the front sight post, his vertical aiming error should be minimal, which usually cannot be detected on the target. Any of these three shot groups could have one round that was pulled by the firer or was a flier (an erratic round over which the firer has no control). Therefore, another shot group must be fired.
NOTE: Location of the shot group Is not important when conducting a grouping exercise. Size of the group and the ability to place two or more groups in the same location are important.
Shot groups — 6 cm or larger The three shot groups shown in Figure G-10 are the easiest to analyze, indicating obvious firer error —improper trigger squeeze is part of the problem. Shot groups that are about 6 cm or larger (about nine squares on the target) are normally the result of the soldier knowing when the rifle is going to fire. Therefore, the instructor/trainer tries to improve trigger squeeze by using the ball-and-dummy technique so the soldier can tighten his shot group (Appendix C). Firers with these shot groups should receive extensive dry-fire training to help correct firing problems.
