An electrifiable projectile for an insect zapper gun is capable of killing a target insect at a distance from the user. The projectile includes a pattern of electric wires forming a front-facing conductive contact structure having a breadth sufficient to allow the projectile to intercept an insect when propelled in a forward trajectory toward an insect. When the projectile's pattern of electric wires comes into contact with the target insect, an electric charge on the projectile is transmitted to the insect rendering the insect deceased.

A bullet with controlled fragmentation has a core in the form of a generally cylindrical body having a forward end and a rear end and intermediate side portions extending there between, the forward end of the core defining a cavity, a jacket encompassing the rear end and at least selected portions of the sides of the core, the jacket having a sidewall having a first drive band portion having a first wall thickness, and a second portion immediately forward of the drive band portion having a second thickness less than the first thickness, the exterior of the jacket defining a cannelure groove encircling the bullet, and the cannelure groove being positioned forward of the first drive band portion. The drive band may have forward edge defining a step. The bullet of the present invention may also be received in the case mouth of a rimless case and be partially protruding therefrom.

An insect zapper gun is capable of killing a target insect at a distance from the user. The zapper gun incudes an electrifiable projectile fired from a handheld base. When the projectile comes into contact with the target insect, an electric charge on the projectile is transmitted to the insect rendering the insect deceased.

A compressive structural element including: an enclosure having a top, a bottom, and inner wall and an outer wall, a first cavity defined between the inner and outer walls and a second cavity defined by the inner wall; and a non-compressible material disposed in the first cavity; wherein the outer wall has at least a portion thereof inwardly shaped toward the first cavity and the inner wall has at least a portion outwardly shaped towards the first cavity such that a first compressive force acting on the top and/or bottom tending to compress the element by a first deflection causes an amplified second deflection, relative to the first deflection, of the inner and/or outer walls into the non-compressible material, thereby exerting a second compressive force against the non-compressible material, resulting in a resistance to the first deflection and the first compressive force tending to compress the element.
