To investigate if there is any correlation between the bullet design and the respective dimensions of the abrasion collar and the skin defect in gunshot entrance wounds, experimental studies were performed on dyed pig skin. For the test shots, .38 Special revolver cartridges with three different bullet designs (round nose, wadcutter, and truncated cone) were used. ⋯ With regard to the entrance hole size, the relationship was inverse. The results are discussed with reference to the pertinent literature concerning the dynamic interaction between bullet and skin.
