The invention relates to a method of making pourable, plastic-bound explosive charges or rocket propellants, to which a metal powder having essentially spherically shaped grains is added. To avoid an increase in the viscosity of the explosive charge or the rocket propellant through polar groups attached to the surface of the metal powder, it is suggested according to the invention that the polar groups of the metal powder be saturated with SiR3 groups (Si=silane; R=organic residue) before the metal powder is added to the explosive mixture. As a result, the polar groups can no longer react with the isocyanates of the explosive charge or the rocket propellant and the specific surface of the respective metal powder, as well as the viscosity of the charges, is reduced.
