The aim of the paper was to investigate and compare the speed and energy of a bullet from 4 mm cal. cartridges of central ignition type M20, both original and transformed by addition of different kinds of propellants. Original cartridges are characterized by an average speed of the bullet of 144 m/s and average energy of 4.8 J. After transformation by the addition of on an average 31.3 mg of smokeless powder from a cartridge type LR'22, a maximum bullet speed of 299 m/s (average) and maximum energy of 21.2 joule (average) were reached. Our test showed that shots using transformed ammunition type M 20 cal. 4 mm can be dangerous for both health and life. Multiple M20 shot wounds may be very similar to single shot wounds caused by a shotshell cartridge fired from a shotgun weapon.
本文的目的是研究并比较来自中心点火式M20型4毫米口径弹药筒的子弹的速度和能量，包括原始的以及添加了不同种类推进剂后改造的弹药筒。原始弹药筒的特点是子弹平均速度为144米/秒，平均能量为4.8焦耳。在平均添加31.3毫克来自LR'22型弹药筒的无烟火药进行改造后，子弹的最大速度达到了299米/秒（平均），最大能量达到了21.2焦耳（平均）。我们的测试表明，使用改造后的M20型4毫米口径弹药开枪对健康和生命都可能造成危险。多发M20枪击伤口可能与霰弹枪发射的霰弹造成的单发伤口非常相似。
