Fire arm projectile, has middle section with guide region, which exhibits common guide length in direction of central axis of projectile, where guide length is between preset percentages of diameter of guide region

摘要

The projectile has a front section (1 '), a middle section (2') adjacent to the front section, and a rear section (3') adjacent to the middle section. The sections are made of steel, and the middle section exhibits a guide region (20 ') with a diameter (D'). The guide region exhibits a common guide length (L') in direction of a central axis (4) of the projectile, where the guide length is between 25 and 80 percentages of the diameter of the guide region. A part of the projectile is coated with a mineral oil, bees wax, graphite, resin, polytetrafluoroethylene or graphite-lacquer coating.
