Abstract (en)
Shotgun pellets consist of virtually spherical bodies exhibiting a knurled surface made up of a plurality of protuberances (13) and depressions (14). The tips (15) of the protuberances constitute virtually deformable external surfaces of the pellets. The protuberances (13) may cover the entire surface of the pellet and have a virtually pyramidal shape, the height of these protruberances (13) with respect to the bottom of the depressions (14) being virtually between 0.15% and 20% of the pellet diameter, preferably around 5% and in any case greater than 15 mu m (micrometer). The pellet may be made from soft iron with Vickers hardness between 80 and 120 HV, preferably between 90 and 100 HV. <IMAGE>
