  • Low-calibre shot gun bullet, especially for shot guns with a partially or fully distended barrel
    Patent number: 6367387
    Abstract: The present invention relates to an under-calibered gun-barrel bullet, in particular for guns with a partially or fully rifled barrel, which is received by a thrust cage. The task of the present invention is providing a further such gun-barrel bullet. This task is solved thereby that the under-calibered gun-barrel bullet comprises a shell jacket (2) which, relative to its loaded position, receives a bullet core (3) displaceable in the direction of the gun-barrel end, whose displacement caused by the blast generation in the shell jacket (2), is limited by an abutment (9) whereby the final form of the gun-barrel bullet (1) is established.
