  • the present invention relates to armour piercing bullets, especially to precision machined armour piercing bullets.
  • This aim of the invention is to design a bullet with improved armour piercing and precision characteristics.
  • the aim is achieved by design of the bullet comprising a bullet housing and a core inserted within the bullet housing, and a tip also inserted in the bullet housing and covering the core from one of its sides or ends in the bullet housing.
