Abstract: A cartridge including a cartridge case for hunting cartridges including a plastic sole body with a first sector forming a wad having an upper damping formed by two parallel cylindrical bodies acting with a balancing effect on a first plate with motion to be driven by a second plate distanced on an axial pin supporting a column bearing a bullet on coaxial clutches into a contact containment cylindrical seat which seat includes two half parts separated by longitudinal cuts perimetrally extending from a disk-shaped deflagration moment for centrifugal, effect the connection points break with contemporary squeezing in opening of the half parts on the inside wall of the barrel and this permits the bullet movement starting with thrust pulse centering to obviate a possible contact with the same barrel also in presence of a narrowing. After shooting of the bullet the two separated half parts follow the bullet along the barrel falling down at the exit of the barrel while the sole body goes out from the barrel.
