The invention relates to hunting weapon ammunition. The inventive bullet comprises an internal arrow (4) whose rigidity is equal to or higher than the rigidity of the bullet body and which is arranged in a hole axially drilled therein. Said internal arrow is offset with respect to the orifice (8) of the axially embodied hole whose diameter is less than the diameter of the internal arrow (4). The wall of the ogival head (3) of the bullet body (2) is provided with one or several deformation notches near the hole. Said invention makes it possible to improve the terminal effectiveness of a small, medium and major hunting calibre weapon with respect to a certain calibre or subcalibre.
