Specific features usually allow recognition of entrance and exit wound
s in bones. Exits are often more irregular, and usually larger than en
trances. The aim of this paper is to compare the size of 17 entrance a
nd exit gunshot wounds from a series of 13 forensic cases. The results
of this work confirm the usually accepted fact that exit wounds in bo
nes tend to be larger than the entrances resulting from the same shot.
In all but one case the exits were larger than the entrances in this
study. Though the bullet loses velocity after penetrating, the ballist
ic behavior (deformation and instability of the projectile) explains t
his tendency. (C) 1998 Elsevier Science Ireland Ltd. All rights reserv
