Abstract

Ammunition for a small-bore weapon operable in the semi-automatic or automatic mode. A round of the ammunition includes a combination of case (12), powder (28) and projectile (24) which enables the projectile to be propelled at subsonic velocity from the weapon to a target while generating sufficient energy to consistently operate the bolt of the weapon and which generates substantially no audible sound during its free flight through air. The projectile (24) of the ammunition is formed from a core (25) including multiple elements (40, 46), each of which is formed from a mixture of heavy metal powder and light metal powder that is densified under high pressure to provide enhanced density of the elements, hence of the core. These elements are incorporated into a light metal jacket (52) by high pressure. A method for the manufacture of the projectile is disclosed.
