The Consumer Product Safety Commission estimates that there are 31,000 airgun injuries annually, 19,000 of which occur in children under 14 years of age. Case reports in the literature include 235 serious and nine lethal pediatric injuries. No experimental model of thoracoabdominal airgun pellet perforation exists. A 60-pound newly killed pig was selected as a model for pediatric airgun injuries. Two commonly available .177-caliber airguns were fired from point blank, 2.5 feet, and 5 feet. A chronograph was used to measure impact velocities for pellets fired at the already-killed pig. Autopsy study of organ wounding was completed. Perforation velocities with point-tip pellets were 407 ft/sec for the thoracic wall and 399 ft/sec for the abdomen. Of the 18 pellets shot at the chest, eight passed through the chest wall, causing 15 organ injuries. Eleven of the 18 pellets perforated the abdominal wall, producing 49 organ injuries.
Airguns create serious intracavitary organ injuries in a porcine model. Moreover, ballistic research is possible in unusual surroundings, such as a packing plant.
消费品安全委员会估计，每年有31000起气枪伤害事件，其中19000起发生在14岁以下儿童身上。文献中的病例报告包括235起严重的和9起致命的儿科伤害事件。目前尚无胸腹气枪子弹穿孔的实验模型。选用一头60磅重的刚宰杀的猪作为儿科气枪伤害的模型。使用两把常见的.177口径气枪在零距离、2.5英尺和5英尺的距离射击。用测速仪测量射向已宰杀猪的子弹的撞击速度。完成了对器官损伤的尸检研究。尖顶子弹穿入胸壁的速度为407英尺/秒，穿入腹部的速度为399英尺/秒。射向胸部的18颗子弹中，有8颗穿过胸壁，造成15处器官损伤。射向腹部的18颗子弹中有11颗穿透腹壁，造成49处器官损伤。
在猪模型中，气枪会造成严重的腔内器官损伤。此外，在诸如包装厂等特殊环境中进行弹道研究也是可行的。
