Abstract:
A cartridge including a cartridge case comprising:a first sector forming a wad and a pair of cylindrical bodies; a second sector including a first plate and a second plate, said first plate being in contact with said cylindrical bodies which act with a balancing effect on said first plate; an axial pin supporting a column having coaxial clutches attached to a bullet having a connector for connection to said clutches; a cylindrical seat comprising a cylindrical member provided with a pair of longitudinal cuts forming two half parts separated by said longitudinal cuts, said cylindrical member having a disk-shaped base forming a bottom portion of said cylindrical member, connection points connecting said half parts to said base; said column having one end extending into said cylindrical seat carrying said bullet and having its other end coupled with said disk shaped base and said first and said second plates; said first sector cooperating with a cartridge case containing gun powder and a firing pin and being positionable within an inside wall of a gun barrel, and upon firing of the bullet in the gun barrel at the moment of deflagration movement for centrifugal effect, a breaking of the connection points happens with contemporary squeezing and opening of said half parts to extend outwardly against said inside wall of said gun barrel whereby to permit movement of the bullet starting with a thrust pulse centering to obviate any possible contact with the inside wall of the barrel in the presence of a narrowing, and after the shooting the two half parts separate and follow the bullet along the inside of the barrel and fall down after exiting from the barrel.
