Deforming bullets like soft-point ammunition and shotgun slugs cause extensive soft-tissue damage. Bullet velocity, construction, and deformation significantly influence injury severity.

Area of Science:

  • Forensic Science
  • Ballistics
  • Trauma Biomechanics

Background:

  • Deforming bullets are designed to expand upon impact.
  • Understanding projectile-tissue interaction is crucial for trauma analysis.

Purpose of the Study:

  • To investigate the effects of deforming bullets on soft tissue.
  • To correlate bullet characteristics with injury severity.

Main Methods:

  • Fired soft-point bullets and shotgun slugs into soap blocks and anesthetized pig hind legs.
  • Utilized multi-flash X-ray to record bullet deformation, breakup, and retardation.
  • Assessed soft-tissue damage through surgical debridement and tissue weighing.

Main Results:

  • Deforming bullets exhibited high energy transfer and caused significant tissue damage.

  • Bullet velocity, construction, and deformation directly correlated with injury extent.
  • Observed extensive deformation and breakup of projectiles within tissue.

    • Conclusions:

    • Deforming bullets pose a high risk of severe soft-tissue injury.
    • Projectile characteristics are key determinants of wound ballistics outcomes.
    • This research provides insights into projectile-tissue interactions and injury mechanisms.
