Abstract (en)
[origin: US4326901A] The present invention relates to a new type of fragmentable charge for weapons of small and medium caliber. The process for the manufacture of fragmentable charges of propellant powder containing nitrocellulose, according to the invention, is characterized in that, in a conventional process for the manufacture of propellant powder containing nitrocellulose, with solvent, a glazing operation is carried out, in which a glazing solution containing at least polyvinyl nitrate and a stabilizer is sprayed onto the grains of powder, and in that, after evaporation of the solvent from the said solution, the grains of powder thus obtained are compressed at between about 80 DEG and 120 DEG . The invention also relates to the fragmentable charges obtained by means of this process.
