Embodiments of a projectile are disclosed herein. According to various embodiments, a projectile includes a substantially solid core of a material, and two or more petals attached to the core. The two or more petals can be formed from the same material used to form the core and can include a trocar tip. A cavity can be bound by the core and inner surfaces of the plurality of petals.

Exemplary projectiles and methods associated therewith including embodiments formed with an internal cavity adapted to receive and retain a cryogenic material into said cavity and then generate a first internal gas upon thermal equalization with said projectile as well as a first internal gas pressure within said cavity. Exemplary embodiments include a structure adapted for maintaining structural integrity after generation of the first internal gas pressure and a second internal gas pressure that is created upon the firing of the projectile. In some embodiments, the second internal gas pressure is more than twice the first internal gas pressure. Some embodiments are adapted with a portion of the projectile formed for displacing away or laterally from an axis formed through a longitudinal center of the projectile upon an impact from striking an object after firing based in part on internal gas pressure and an impact at cavity wall section rupture zones.

The present invention relates to a projectile, in particular deformation and/or partial fragmentation bullet, comprising an essentially cylindrical projectile tail, an adjoining bow sided projectile head with an essentially central opening which opens into a cavity that extends axially from the projectile head in the direction of the projectile tail, preferably into the projectile tail, which has a cavity bottom and is bounded by a wall, and an tear-off groove introduced into the wall and, at least partially surroundings the cavity, which is arranged at a distance of at least 10% of the longitudinal extension of the cavity from the cavity bottom and has a radial depth of at least 10% of a caliber diameter and/or of at least 30% of a radial wall thickness of the wall surrounding the cavity.

A projectile including a body having a longitudinal axis, a front end and a rear end at respective ends along the longitudinal axis, and a surface profile extending from the front end to the rear end, wherein the surface profile is radially symmetrical about the longitudinal axis, the body having a caliber size defining a largest diameter of the body along the longitudinal axis. The projectile also includes two or more radially-protruding stress-concentrating protrusions arranged proximate the front end of the body.

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.
