The invention relates to ammunition for firearms, as smooth and a rifled barrel. The projectile with rigid attached to the housing stabilizing fletching block, plates of fletching block have a continuation on the housing, centering the projectile in the barrel. In the offered variant, on the friction and heat of the bullet and the barrel takes about 1% of the shot energy, besides low vibration. The rest of energy escapes to destination, and that's good. Erasing minimal of the barrel. Application of the projectile in the shotgun and rifle barrels increases the service life of barrels. Use of such projectiles increases the initial speed, and with the sleeve-nozzle and a second charge, allows to increase the speed and specialization of the projectile. At the expense of the aerodynamic and gyroscopic effects, increases the lethal effect over long distances, due to the greater energy saved, improve the close grouping of shots and flat trajectory.

1. A projectile comprising: a body having a central core;a fletching block rigidly attached to the body;wherein the fletching block is made of non-ferrous metals or non-ferrous alloys;the fletching block including stabilizing plates that extend substantially along an entire length of the body,wherein the stabilizing plates are fixed in an annular groove in the body, for centering the projectile inside a barrel,wherein an area of the stabilizing plates increases towards a proximal end of the fletching block, for aerodynamic stabilization of the projectile, andwherein the stabilizing plates extend radially from the body to a larger maximum diameter than a diameter of a barrel from which the projectile is fired. 2. The projectile of claim 1, wherein the stabilizing plates are aligned with a longitudinal axis of the body. 3. The projectile of claim 1, wherein the stabilizing plates are misaligned relative to a longitudinal axis of the body by several degrees. 4. The projectile of claim 1, wherein the body is made of steel, high strength plastics, non-ferrous metals, or non-ferrous alloys. 5. The projectile of claim 1, wherein the annular groove is at a distal end of the body. 6. The projectile of claim 1, wherein the central core is a metallic core, and has a cavity at its proximal end in a shape of a polyhedron. 7. The projectile of claim 1, wherein central core is a metallic core, and has a cavity at its distal end with a screw thread. 8. The projectile of claim 1, wherein central core is a metallic core, and wherein the metallic core has a protrusion in a shape of a polyhedron. 9. The projectile of claim 1, wherein central core is a metallic core, and wherein the metallic core has a protrusion with a screw thread. 10. The projectile of claim 1, wherein the fletching block has a protrusion in a shape of a polyhedron. 11. The projectile of claim 10, wherein the fletching block has a cavity in a shape of a polyhedron. 12. The projectile of claim 11, wherein the protrusion of the fletching block is inserted into the cavity in the body. 13. The projectile of claim 1, wherein the central core has a protrusion which is inserted into a cavity in the fletching block. 14. The projectile of claim 13, wherein the body, the core, a cap and a sleeve-nozzle are integrally made from steel, nonferrous metals copper, or alloys thereof. 15. The projectile of claim 1, wherein a proximal end of the body includes a thread at its inner edge. 16. The projectile of claim 1, wherein the projectile includes a joint sleeve-nozzle which is threaded to a bottom of the body. 17. The projectile of claim 16, wherein the nozzle-sleeve is made of steel non-ferrous metals, copper, or alloys thereof. 18. The projectile of claim 16, wherein the nozzle-sleeve has recess cuts that extend to the body. 19. The projectile of claim 16, wherein the nozzle-sleeve includes an inner hole which is filled with an additional propellant. 20. The projectile of claim 1, wherein the projectile includes a wad-obturator made of plastic.
