Abstract

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.
