Claims16
A propellant charge projectile, wherein the propellant charge projectile comprises a mixture comprising metal and 2 to 15% by weight of plastic, based on the total weight of the propellant charge projectile,
- wherein the metal in the propellant charge projectile is present in the form of particles, and
- wherein the particles have a spacy, lamellar, dendritic or spherical morphology or are present in a mixture of two or more of these morphologies.
A projectile, wherein the projectile is made from a mixture comprising metal and 2 to 15% by weight of α-olefin-vinyl ester copolymer, based on the total weight of the projectile, and wherein the α-olefin-vinyl ester copolymer is an ethylene-vinyl actetate copolymer with a proportion of vinyl acetate of 9 to 18% by weight, based on the total weight of the ethylene-vinyl actetate copolymer.
A projectile, wherein the projectile is made of a mixture comprising metal and 2 to 15% by weight of thermoplastic elastomer, based on the total weight of the propellant charge projectile,
- wherein the metal in the projectile is in the form of particles and the particles have a median diameter D50 of 5 to 100 μm, and/or a D10 of 2 to 65 μm, and/or a D90 of 10 to 150 μm, and
- wherein the metal in the projectile is in the form of particles and a width of the size distribution of the particles is from 1 to 6, the width of the size distribution being defined as (D90-D10)/D50.
