A rifled barrel has a cylindrical channel longitudinally extending within the rifled barrel between an oppositely oriented muzzle opening and a breach opening, the cylindrical channel having a rifled portion and a non-rifled portion, the rifled portion having a land and a groove helically extending along a surface of the cylindrical channel from the muzzle opening toward the breach opening, the non-rifled portion being smooth and having a consistent diameter along a length. The diameter of the non-rifled portion of the cylindrical channel is equal to a diameter of the rifled portion measured between oppositely oriented sections of the groove. A transitional section of the rifled portion has a diameter measured between oppositely oriented land sections that gradually decreases along a section of the rifled portion adjacent to the non-rifled portion until equaling the diameter of the non-rifled portion.

A bullet projectile is described wherein an internal cylindrical sliding mechanical hammer mechanism provides secondary impact improving overall effectiveness in delivering a mechanical shock wave to a target.

A bullet including a drag-reducing assembly provided about its main body, and configured for being triggered upon a blast from a cartridge, in order to reduce a resulting base drag of the bullet during flight trajectory. The drag-reducing assembly includes at least one cavity being configured for receiving and containing a portion of gun gas from the cartridge and corresponding blast, and at least one peripheral orifice for releasing gun gas from the at least one cavity during the flight trajectory of the bullet, in order to fill a partial vacuum behind the bullet during flight trajectory, and thus reduce the resulting base drag, for an improved overall ballistic performance of the bullet.

Disclosed are ammunition and ammunition tracking systems. The ammunition and ammunition tracking system may include a first projectile and a marker. The marker may be associated with the first projectile. The marker may contain a unique signature such that the first projectile may be identifiable from a second projectile.

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 the 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 projectile for firearms is provided, which is designed as a slender rotation body for ultrasonic velocity, having an approximately cylindrical center part, a tip on the front end and a tail on the rear end which tapers conically toward a projectile base, wherein the projectile is designed such that the circumferential flow remains uniform over the entire trajectory thereof from a front shock wave, through a boundary layer enclosing the projectile body to a rear tail vortex.

The present invention comprises a novel device, a ceramic cap that is firmly attached in a manner that prevents relative rotation axial movement or separation between the modified tip of an existing bullet and said cap to allow the modified bullet to shatter the glass of an automotive or truck windshield on contact, thus allowing the bullet to pass through the glass with a reduction of deflection incurred by non-modified bullets while producing larger bullet holes and areas of glass disruption than non-modified rounds and increasing the quantity and size of injury inflicting shrapnel.
