A stacked, collaborative engagement ammunition round is presented. The round includes plural stacked miniaturized projectiles where such projectiles separate after launch and then swarm as a group towards a target or targets. At launch, the projectiles may fly in a preselected formation, leader-follower towards the target. Or, the projectiles may deploy propellers, tri-copter or quad-copter vanes, and self steer swarming to the target. Each projectile has its own miniaturized guidance, navigation and control components, autopilot, cameras, transmitter, receiver, antennae, power source, sensors, fuzes and/or flex circuits.

The present invention provides a projectile device and a method of manufacture of a projectile device and in particular, to a pistol bullet and a rifle bullet and method of manufacture of same. In one embodiment, the projectile apparatus has a cylindrical body portion having a diameter, a front nose section tapering from a most proximal point of the projectile to the cylindrical body portion, and a rear tail section connected to the body portion and extending to the most distal point of the projectile, in which the front nose portion comprises a plurality of twisting depressions forming troughs.

A less-lethal projectile includes a cylindrical flexible body. The body includes a nose, a conical tail, and a tubular sidewall. The tail and sidewall extend rearwardly away from the nose. The sidewall defines an interior space around the tail. A flowable medium is received in the interior space around the tail. The flowable medium is configured to deform the sidewall upon impact of the nose with a target such that a portion of the sidewall contacts the target around the nose. Impact of the nose with the target causes the flowable medium to move forward in the interior space around the tail and expand the sidewall radially outward and forward such that the sidewall contacts the target around the nose.

A projectile is improved aerodynamically by cutting grooves having parabolic transitions between the depth of the groove and the bearing surface. An ejectable tip is attached to the leading edge of the projectile to facilitate greater ballistic coefficient during flight and improved expansion upon impact at a soft target.

The present invention relates to longitudinally sectioned bullets and methods that pertain to a projectile structured to be discharged from a firearm and comprising at least two separable longitudinal body sections and at least one binding element that holds the at least two longitudinal body sections together, such as before impact with a target. Said projectile is thus capable of controlled fragmentation against a soft target. Said projectile is adapted to also contain at least one supplemental payload deliverable to a target to further damage said target.
