[Grazing gun shot wounds (author's transl)].
The ballistics of graze shots without bullet contact were investigated. Shots from several heights and distances were performed on stretched elastic bandages nearly tangentially. With shots from short distances there were soot stripes transverse to the shot direction within the picture of partially and uncombusted powder residues upon the elastic bandages, not yet described in the literature. The phenomenon of getting reproducible stripes within the graze shot effects were studied by photos taken by a high speed camera (nearly 4,000 and 7,000 pictures/s). Just when the shot broke off, stationary waves were inflicted within the elastic surface by the shot streams. The white stripes within the graze shot effects were in the shot stream shadow when the hot powder gas and uncombusted residues went over the elastic bandages. The physical and theoretical aspects were explained and concrete case was demonstrated. The investigation of graze shot effects is a new possibility to determine short shot distances.
