ABSTRACT:
A cartridge for firearms, comprising a shell (1), a primer disposed in the shell, and a liquid space containing a liquid (5) to be spread on the inner surface of a barrel. According to the invention, the liquid space (3a) is formed by a cylinder within which there is mounted a piston (4). When the primer (2) is detonated by the action of a firing pin, the piston (4) propels the liquid (5) in front of it, whereby the liquid (5) expels a plug (6) from the orifice through which oil is to be sprayed and spreads as a spray on the inner surface of the barrel.
