5.1 Ground - All reference to ‘the ground’ in the following position
rules are to be construed as the surface of the firing point, floor,
or shooting mats. No portion of the competitor’s body may contact the
ground ahead of the firing line (see also Rule 6.1), although those portions
of the competitor’s body or rifle which do not contact the ground
may extend ahead of the firing line.
5.8 Sitting - Weight of the body supported on the buttocks and
the feet or ankles, no other portion of the body touching the ground.
The BB gun will be supported by both hands and one shoulder only.
Elbows may rest on the legs at any point above the ankles. (The elbow
is defined as 4 inches from the point of the arm when bent.) No portion
of a competitor’s foot may cross the firing line
6.1 Firing Line - The firing line is immediately in front of the firing
point, and must be marked so that it can be clearly seen by coaches
and competitors. The shooting distance is measured from the firing
line edge closes to the competitor to face of the targets.
