Abstract: A process of producing a propellant charge igniter for cartridge ammunition of the type including an ignition tube with a booster charge, wherein the ignition tube is composed of a sheathing tube (4) with ignition openings (3) and a thin-walled protective tube (6) which is arranged inside the sheathing tube (4) in order to protect the booster charge, and wherein the external wall of the protective tube fits against the internal wall of the sheathing tube (4) and covers the ignition openings (3). To avoid microscopic gaps between the sheathing tube and the protective tube, which gaps influence the performance of the propellant charge igniter, a paste-like sealing agent (5) is introduced into the sheathing tube (4) before the protective tube (6) is inserted into the sheathing tube (4), and only then is the protective tube (6) inserted into the sheathing tube (4) to displace the sealing agent.

Abstract: A protective surface coating for ammunition having no cartridge casing and ammunition having a combustible cartridge casing. A body of highly porous nitrocellulose is permeated from the outside with a polymer carried by a solvent to form a binder for the body. A layer of metal platelets containing air-pockets is bound to the body with a binding polymer. The metal platelets are covered with an outer coating of a rapidly curing resin. The protective coating is used to prevent the penetration of moisture into the porous cartridge casing or into the powder mass itself and to provide improved stability to heat and flames.
