[Wounding capacity of bullets after ricochet from sand or concrete (author's transl)].

Investigation is made upon the ricochet of different bullets (full jacketed and soft nosed) from concrete or sand. The deformation resp. disintegration of the bullets depends on the target material, on the design of the bullet and on the striking velocity. The major resulting bullet fragments are classified following their depth of penetration into pinewood, thus giving an approximate measure of their danger to man. The relation between angle of impact, angle of ricochet and the criteria mentioned above is shown in graphs.
