Bullet, weapon provided with such bullets, kit for assembling the same, and corresponding methods of manufacturing, operating and use associated thereto
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.

Bullet, weapon provided with such bullets, kit for assembling the same, and corresponding methods of manufacturing, operating and use associated thereto
The present disclosure concerns a bullet (1) configured to be propelled by a blast of a cartridge, the bullet comprising a main body (3) provided with an internal body cavity (7) and having a frontward section and a rearward section provided with an opening in fluid communication with the internal body cavity, the internal body cavity by means of the opening being capable of recovering a portion of gun gas resulting from the blast of the cartridge. The present disclosure further comprises a weapon having such a bullet, and a method for reducing drag from a bullet propelled out of a barrel of a weapon.
