[Biomechanical-clinical interpretation of firearm wounds. General problems. VIII. Propedeutic ABC of terminal ballistics]

The Authors, consistent with their aim to compare and contrast the two protagonists of bullet wounds, namely the bullet and its soft human target, delineating their respective profiles, strengths and weaknesses, feel obliged to dwell at some length on the most frequently pathogenetic regulation firearms. Up until the early twentieth century bullet wounds could be generically classified among the forms of open traumatism, but with the advent of high-speed bullets they have come to take on a unique profile of their own, setting against the old permanent cavity due to mechanical insult a new type of transitory ghost, the definition of which as a cavity would merely be an oversimplification in theoretical terms. Can we really attribute this somewhat privileged dimension to bullet wounds today or must we relegate them once again to the sphere of mechanical traumatisms, albeit with a new inflammatory key to their interpretation, making the most in this sense of the contribution provided by the speed of the bullet? The literature is abundant, but uncertain; we intend to attempt an answer to this tricky question in the following pages, devoted more properly to terminal ballistics. Undoubtedly, the new speeds have had a substantial impact on the wounds inflicted upon the soft target, but the streamlining of the jacket has modified and even offset the results, giving rise to the unexpectedly humanitarian bullet, later subject to reappraisal in military quarters as tactically more efficient, because it obliges the enemy to employ greater resources for recovering, assisting and healing the wounded. We can safely claim that ballistic science in the field of light or portable firearms is experiencing a contradiction between the speed of the bullet and the streamlining of the jacket which makes this speed possible, but which undermines the efficacy of the often unconfessable results. Short-barrelled firearms, which on account of their defensive role, the alibi of their problematic access to speed, and their characteristic use as "last-chance" weapons, are less subject to international constraints and enjoy an extensive civilian market with specific claims to stopping power, thus become the true witnesses to a reality no different to the one Dum-Dum interpreted: the field of modern regulation firearms is shrouded in similar doubts, strengthened by the increasingly short barrels of the weapons, remedies and temptations, with, in addition, the increasingly precarious nature of the human element behind the firearm.(ABSTRACT TRUNCATED AT 400 WORDS)
