Abstract

A short range trajectory round having an aerodynamic resistance which sharply increases at a predetermined time after discharge of the round from a barrel of a weapon. The round includes a body having a longitudinal axis and a forward tip portion and a rear base portion with at least one segment forming a part of the body and arranged for outward movement away from the longitudinal axis. The at least one segment at least partially delimits an inner cavity within the body terminating at a predetermined distance from the tip portion, and a plunger having a forward portion and a rearward portion is disposed within the cavity and arranged for movement in the longitudinal direction of the round between at least a rearward position and a forward position. the plunger is movable to the forward position in response to the firing of the round for form-lockingly engaging the at least one segment to prevent movement of the at least one segment away from the longitudinal axis of the round thereby to establish a first aerodynamic resistance for the round. The plunger is also movable toward the rearward position after discharge of the round from the barrel of the weapon for disengaging the at least one segment to enable outward movement of the at least one segment with respect to the longitudinal axis of the round and thereby establish at least a second aerodynamic resistance for the round which is greater than the first aerodynamic resistance.
