A rifled slug is provided with a metal head (1) and a plastic rear part (2), which is made as a single piece from a pin-shaped front part (5), with a rod-shaped middle part (6) joined to the rear of the front part, and with a plunger-shaped rear part (7).

A rifled slug is provided with a metal head (1) and a plastic rear part (2), which is made as a single piece from a pin-shaped front part (5), with a rod-shaped middle part (6) joined to the rear of the front part, and with a plunger-shaped rear part (7). The front part (5) is inserted from the rear into a pocket hole of the metal head (1) and is joined thereto in a captive manner. This improves a rifled slug of the aforementioned type by increasing the precision, i.e. reducing the dispersion in the target. To this end, the front part (5) is provided in the form of a hollow body and is joined to the middle part (6) via a predetermined breaking point (14), whereby when shooting, the middle part (6) slides into the cavity of the front part (5) until the upper surface (19) of the rear part (7) strikes the lower surface (20) of the front part (5).

The invention claimed is: 1. A gun-barrel projectile comprising: a metal head having a blind hole; and a one piece, plastic rear part comprising a pin-shaped anterior part, a rod-shaped central part and a piston-like posterior part, and wherein the anterior part has a cylindrical body with a hollow space and inserts rearwardly into the blind hole of the metal head and is captively connected therewith, and is rigidly connected to the central part via a predetermined breaking point such that the lower surface of the anterior part is separated from the upper surface of the posterier part by substantially the length of the central part, whereby after firing the predetermined breaking point rends allowing the central part to then be pushed into the hollow space of the anterior part until the upper surface of the posterior part contacts the lower surface of the anterior part. 2. The gun-barrel projectile according to claim 1, wherein the anterior part is provided with air channels, which make possible a flow of air forced into the hollow space of the anterior part upon penetration of the central part. 3. The gun-barrel projectile according to claim 1, wherein barb-shaped sections are provided on the central part, which upon penetration of the central part into the hollow space of the anterior part grab behind a flange in the walls of the hollow space of the anterior part. 4. The gun-barrel projectile according to claim 2, wherein barb-shaped sections are provided on the central part, which upon penetration of the central part into the hollow space of the anterior part grab behind a flange in the walls of the hollow space of the anterior part.
