[Wound ballistics of extremely short-range shotguns]

A 45-year-old man died from a homicidal shotgun wound of the neck. The autopsy showed that the plastic shell retaining cup had entered the body after the mass of the shot; the dispersion of the individual pellets was about 12 cm already. The perpetrator had used a conventional signal pistol equipped with a hand-made steel barrel, gauge 12, length 20 cm, and ammunition with 3 mm pellets (shot no. 5). By means of experimental shots with a similar weapon it could be proved that the entire shot including the plastic shell retaining cup can penetrate the skin at a muzzle-victim range of less than 2 m.
