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

A bullet for use with a cartridge for propulsion out of a barrel of a weapon, the bullet comprising:

• a main body acting as a projectile;
• and
• a drag-reducing assembly provided about the main body, and configured for being triggered upon a blast from the cartridge, in order to reduce a resulting base drag of the bullet during a flight trajectory, the drag-reducing assembly comprising:
• at least one cavity being disposed within a portion of the main body, and being configured for receiving and containing a portion of gun gas from the cartridge and corresponding blast thereof, the at least one cavity including a cross-sectional profile being substantially constant along a given segment of a longitudinal axis of the bullet;
• and
• at least one peripheral orifice provided about the main body of the bullet and in fluid communication with the at least one cavity, the at least one peripheral orifice being configured 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 of the bullet during flight trajectory, for an improved overall ballistic performance of the bullet.
