摘要： A firearm insert has an insertable barrel (27) and a loading shell (21). The mass ratio between the inner and outer diameters of the insertable barrel (27) exceeds 60 % when the inner diameter has less than 5 mm and the outer side of the insertable barrel (27) is totally smooth, so that it closely fits into the barrel of the firearm. The corresponding loading shell (21) is made of two separable parts (1, 10). In the front female part (1) the small caliber ammunition (7) to be fired can be introduced. The rear male part (10) contains in its inner bore an axially movable firing pin (11). The rear part (10) of the loading shell is plugged into the front part (1) and secured by means of a bayonet catch. The assembled loading shell (21) together with the charge (7) has the same outer dimensions as a usual cartridge for the concerned firearm and can be handled as such. In particular, several loading shells (21) may be stored in the magazine of the firearm, so that rebading requires only a manual loading movement. The grooves (28) and lands (29) in the disclosed insertable barrels (27) are produced by cold forming by hammers arranged around the periphery of a stationary core that extends over the whole length of the barrel (27). The hammers form a standard tube whereas the barrel (27) worked by the hammers is twisted and drawn off the core.

摘要： The insert consists of an insertable barrel (27) and a loading shell (21). The ratio of the dimension of the inside to the outside of the insertable barrel (27) amounts to more than 60% in the case of an inside diameter of less than 5 mm, and its outer side is completely smooth so that it fits accurately into the bore of the rifle that is to be used. The associated loading shell (21) consists of two separable parts (1, 10). The ammunition (7) of smaller diameter that is to be used can be inserted into the front, female part (1). The rear, male part (10) contains a firing pin (11) that can move axially in a drilling that is incorporated in this part. The rear part (10) of the loading shell is inserted into the front part (1) and secured by means of a bayonet lock. The outside shape of the assembled loading shell (21) that is provided with a charge (7) corresponds to that of a conventional rifle cartridqe for the particular firearm and can be handled in the same way as such a cartridge. In particular, a plurality of loading shells (21) can be loaded into the rifle magazine, and reloading requires only a manual loading movement. The grooves (28) and the lands (29) in the insertable barrel (27) according to the present invention are produced by means of a cold-forming process, in that hammers that are arranged around the periphery of a stationary core that extends to the whole length of the barrel (27) form a standard tube, while the barrel (27) that has been produced is withdrawn from the core, under the hammers, whilst being appropriately rotated.
