Some common types of "humane killers" are supplied with rubber bushings and recoil springs holding back the bolt, which afterwards is rebound into the barrel. Removal of the rubber bush and withdrawal spring before firing can cause the bolt to break and become a free projectile. A suicide case is reported, in which a livestock stunner discharged a steel bolt penetrating the forehead and getting stuck in the skull.
一些常见类型的“人道杀手”配备有橡胶衬套和阻止枪栓的后坐弹簧，之后枪栓会回弹进枪管。开枪前移除橡胶衬套和后坐弹簧可能会导致枪栓断裂并成为一枚自由弹射物。据报道有一起自杀案件，其中一名牲畜电晕器射出的钢栓穿透前额并卡在头骨中。
