A series of 20 shots with the AK-74 Russian Assault Rifle, in which the entire course of the bullet was captured in gelatin, showed a change in direction of the bullet track approximating a right angle in every case. Bullets were recovered from the gelatin for ten consecutive shots of this series and examined roentgenographically. In all cases an internal deformation was discovered to have taken place: lead from the bullet's core flowed into the air space inside the bullet's tip. The roentgenograms also showed that this flow of lead resulted in an asymmetrical bullet in every case. We suggest this resulting bullet imbalance as a possible cause of the unusually marked curve in this bullet's path through tissue.
使用AK - 74俄罗斯突击步枪进行了一系列20次射击，子弹在明胶中的整个轨迹都被记录下来，结果显示每次子弹轨迹的方向变化都接近直角。在这一系列射击中，连续十次从明胶中取出子弹并进行X光检查。在所有情况下，都发现子弹内部发生了变形：子弹芯的铅流入了子弹尖端内部的空隙。X光片还显示，每次这种铅的流动都会导致子弹不对称。我们认为这种子弹失衡可能是导致子弹在穿过组织时路径出现异常明显弯曲的原因。
