1. A composed projectile for subcalibre projectile comprising a sabot, a projectile as having a front end and rear end and a driving speculum, wherein the composed projectile has geometry, which is substantially cylindrical, that said composed projectile comprises a projectile made of a metal material, that the length of the composed projectile is not substantially longer than the projectile, that the sabot is arranged to substantially enclose the subcalibre projectile, said projectile also includes a rearward facing end that has a patterned surface to produce a friction and/or interference joint with said driving speculum to support transfer of rotation from movement of the composed projectile through a bore/barrel, the sabot has a front part which is divided into at least four sectors, which sectors are arranged to fold-out a part of the sabot in a controlled manner, an upper part of the sabot is provided with through-going cuts running from the periphery of the sabot and up to a projectile receiving space, which cuts are arranged to run from a front end of the sabot to essentially to a level of a shrink indentation, the sectors of the sabot are arranged to be rapidly fold-out from the geometry of the sabot with a bending direction of said shrink encroachment in a controlled manner, the rear end of the projectile has a rearward conical ending, and that the driving speculum has a substantially cylindrical collar, which is arranged to enclose a corresponding cylindrical contraction at the rear end of the projectile and of the sabot. 2. A composed projectile according claim 1, wherein the projectile at its said rearward facing end comprises one or more recesses which are arranged to cooperate with said driving speculum to support transfer of rotation from the movement of the composed projectile through a bore/barrel. 3. A composed projectile according to claim 1, wherein the sabot has a peripherally running shrink encroachment arranged to receive a contraction of a casing receiving said sabot. 4. A composed projectile according to claim 1, wherein the sabot is designed to be able to be fed in all types of PDWs in the form of pistols, machine guns, or automatic weapons that are in the form of carbine and light support weapons. 5. A composed projectile according to claim 4, wherein the projectile is made of a high-density material. 6. A composed projectile according to claim 5, wherein the density of the metal material is greater than or equal to 17.5 g/cm 3 . 7. A composed projectile according to claim 5, wherein the projectile has a density of at least 12 g/cm 3 , preferably at least 15 g/cm 3 . 8. A composed projectile according to claim 7, wherein the projectile is made of a wolfram alloy having a density of at least 17.5 g/cm 3 . 9. A cartridge having a subcalibre projectile, wherein comprises a composed projectile in accordance with claim 1. 10. A cartridge according to claim 9, wherein the composed projectile having a caliber of 4 to 15 mm is introduced in a casing. 11. A cartridge according to claim 10, wherein the composed projectile is introduced in a casing of metal. 12. A cartridge according to claim 11, wherein the casing is made of aluminum. 13. A cartridge according to claim 11, wherein the casing is made of brass. 14. A cartridge according to claim 9, wherein the casing and composed projectile are arranged to be able to be fed in all types of weapons. 15. A process for the manufacture of a composed projectile according to claim 1, wherein a projectile is introduced from behind into a sabot whereupon the sabot is sealed by means of a driving speculum. 16. A process according to claim 15, wherein the driving speculum seals the sabot by being thread over the rear end of the sabot. 17. A projectile for subcalibre ammunition and being part of a composed projectile according to claim 1, wherein it comprises a front conical or ogival part and a rear, substantially cylindrical part, wherein the rearward facing surfac e of the rear part is provided with a patterned surface to provide a friction or key interference with a driving speculum intended to cooperate with the projectile.
