Exploding Targets in Recreational Use

Abstract

Exploding targets are marketed for their ability to indicate long-range marksmanship by detonating upon high velocity impact. The Internet has popularized recreational use of these targets outside of the scope of their intended design. We present a case of a 47-year-old man who was a bystander during recreational use of exploding targets. A .300 Winchester Magnum rifle was used to detonate an exploding target, on top of which was placed a fire extinguisher inside an aluminum pipe. The decedent was struck in the abdomen by a fragment of aluminum and collapsed. Despite emergency efforts at the scene, he was pronounced dead. Scene investigation revealed aluminum fragments throughout the blast radius. External examination and postmortem radiograph showed an entry wound of the left mid-abdomen without evidence of retained shrapnel. The autopsy findings included a hemoperitoneum due to transection of the right common iliac artery and inferior vena cava. A 10.6 g fragment of aluminum was recovered from within the abdomen. This case illustrates a dangerous misuse of exploding targets that has been popularized in the media. It also exemplifies a potential pitfall of a negative radiograph, despite the presence of metal shrapnel, because of the radiolucency of aluminum.
