Ammunition for small or medium caliber hunting fire-arm, including a case secured to a base carrying a primer; a projectile contained in the case and constituted by a subcaliber bullet having at least a head forward of the ammunition and a feathering rearwards thereof fixed to said head and a sabot having the caliber of the hunting fire-arm; a chamber disposed between the sabot and the base and filled with a propellant charge for propelling the projectile when the propellant charge is fired; said feathering including at least a leading edge facing forwards of the subcaliber bullet which is driven at supersonic speed at the fire-arm outlet and which has a center of gravity located on its centreline axis and an aerodynamic center of pressure located on the centreline axis rearwards of the center of gravity; said ammunition further comprising means for destabilizing said subcaliber bullet on its trajectory beyond a distance travelled outside of the fire-arm and comprising the aerodynamic center of pressure of the subcaliber bullet being arranged at the point of meeting of the leading edge of the feathering with the centreline axis of the subcaliber bullet and at a distance from the center of gravity of the bullet lying between one half of and twice maximum diameter of the subcaliber bullet without the feathering.
