The armour-piercing bullet is designed for firearms used for the destruction of the enemy manpower. It has increased piercing action and 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 the said envelope (1), wherein said envelope also includes a sleeve (2). The ratio between the surface areas at the central cross-section of the core (3) and the bullet ranges from 0.3 to 0.4, while the ratio between their masses is at least 0.45 and the ratio between the thickness of the envelop (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).
