22. The shots  Up to 2 M the whole shots enter the body in one mass producing only one central hole.  At 2 M and more start of dispersion hole and few surrounding separate shots hole.  At 3 M the central hole is smaller in size with increased dispersion of shots holes.  At 4 M complete dispersion of shots holes having a circular diameter of about 16 cm.

24. The shots  In longer distance, the spaces between the shots are increased and the power of penetration of shots is decreased.
