This paper deal with the comparison of relative wounding potential of guns, which we know from childhood, specifically blowpipe and slingshot. Many people played with these guns in childhood without knowing how dangerous these guns are. Because this area has not been examined enough, this paper focuses on it. The relative wounding potential is examined through an experimental method. This method is indirect and includes shooting to the replacement material, which was gelatine with a concentration of 20 %. Using a high-speed camera, the course of missiles in the target, from penetration to stopping, is recorded. The volume of the temporary cavity is determined by image analysis, and subsequently, the relative wounding potential is calculated. Other monitored parameters are the depth of penetration of the projectile and the impact velocity of the projectile. Then, it is possible to determine the transmitted kinetic energy of the projectile. The results should help to assess the dangers of these "children's" weapons and alert society to their risks. They can also serve to experts in the field of ballistics and forensic expertise.
In the world, there is an increasing trend in the use of weapons. This trend is also reflected in expansion weapons. For example, in the Czech Republic, the increase is quite marked. This is both legal use in defense and illegal use. This fact needs to be addressed. This article deals with the wounding potential of expansion weapon. A ballistic experiment was used to Assess the potential of the expansion weapon. A non-homogeneous block of ballistic gelatin was shot by an expansion weapon from a relative proximity. Sprue tracking was recorded using a high-speed camera. The monitored parameters were the shape, dimensions and volume of the permanent and temporary cavity created in ballistic gelatin. Subsequently, the injury profile method was applied. The results were subjected to quantitative and qualitative assessment. The acquired findings can be used in the field of forensic medicine, war surgery, traumatology and experimental ballistic balancing.
The topic of shooting weapons is very expended. Some people say that shooting weapons are dangerous. Other people say that people who own shooting weapons are dangerous. The truth lies probably somewhere in the middle. However, the issue of shooting weapons still needs to be addressed. Awareness of their occurrence, the wounded effect, and the appearance needs to be extended even among the lay public. Nowadays, it is needed twice. People are misinformed by media or they know incomplete or even the twisted truth. Most laymen cannot tell what is possible and what is already not possible from those information. Most shooting weapons look as the same but they can be only so-called "toys" or freely available copies.
In the last few years, it has been possible to see an increasing trend of aggression in society, leading to the more frequent use of weapons in conflicts. The using of air weapons is also increasing. But are these weapons really dangerous, and what is the effect of shooting distance on the depth of the shot? The article tries to answer these questions. The paper uses ballistic experiment to gain knowledge on which a qualitative evaluation is used. The shooting experiment is based on the firing of physical substitution models made of 20% ballistic gelatine from an air gun with a calibre of 4.5 mm, at a distance of 5, 10, 15, 20 and 25 m. The impact velocities of the projectile were measured using optical ballistic gates and using high-speed cameras were recorded missile passes ballistic gelatin. The depths of the shots were then measured using callipers, and the maximum dimensions and the shape of the temporary cavities of the shots were determined using optical recordings from the high-speed camera. It was found that the depth of the shot decreases with increasing shooting distance. The same applies to the maximum volumes of temporary cavities. These trends are almost linear and are associated with a drop in the impact velocity of the projectile hitting the test target. This pilot experiment serves for the initial verification of the hypothesis of the effect of shooting distance on the depth of shot in air gun weapons and provides essential information for further in-depth investigation.
