This is an old Aiming Drill used to teach recruits proper & consistent Sight Picture, prior to Live Firing.

The men at the wall (scorers) are moving a 'Bulls-Eye' over a blank piece of paper, tacked to the wall.

The "shooters", men behind the stationary rifles, call out when the sights are aligned with the moving Bull.

The "scorer" stops the Bull and marks the paper with a pencil 'dot', through the center of the Bull, when so ordered by the "shooter".

This is repeated multiple times.

A close grouping of pencil dots indicates the "shooter" has a consistent sight picture.
