The present invention relates to an armour-piercing bullet intended for firearms used for defeating the vital forces of an opponent provided with individual armoured protection. The purpose of this invention, which also relates to a method for manufacturing this bullet, is to increase the piercing action of said bullet. The armour-piercing bullet of the present invention includes an envelope (1) with a head portion (A), a leading portion (B) and a tail portion (C). The envelope (1) also includes a piercing core (3) which is mounted in the head portion (A) so as to protrude therefrom, and which is attached to the inner surface of the tail portion (C) of said envelope (1), wherein said envelope also includes a sleeve (3). The ratio between the surface areas at the central cross-sections of the core (3) and of the bullet ranges from 0.3 to 0.4, while the ratio between their masses is at least of 0.45 and the ratio between the thickness of the envelope (1) in the tail portion (C) and the diameter of the core (3) ranges from 0.1 to 0.2. This invention also relates to a method for manufacturing this armour-piercing bullet having a piercing core (3) protruding from the envelope (1), wherein said method involves press-fitting the core (3) with the sleeve (2) into the envelope (1) and crimping the head portion (A) of said envelope (1). While crimping the head portion (A) of the envelope (1), the method also involves simultaneously crimping the tail portion (C) of said envelope (1) about the core (3).
