Radiological findings in gunshot wounds caused by hunting ammunition. An experimental study.

Experimental gunshots were made with hunting ammunition using a dummy model made of skin and foam rubber as the target. After penetration of intermediate targets of wood by the bullets, the characteristics of the wounds changed and their dimensions increased. The morphology of the wounds presented a very varied spectrum. When the gunshots had initially passed through wood 50 mm thick, radiographs of the skin showed a quantity of metallic residues between 10 microns and 1 mm. The metallic particles were wiped off the surface of the projectile by the target itself, whereby the best "wipe-off effect" was achieved with skin. The experimental findings suggest that the formation of the fine metallic residues is analogous to the development of the bullet wipe formed by lead bullets. Larger fragments flew into the target independently of the bullet and depending on the distance between the intermediate and final targets. A case example is documented.
