[Double ricochet marks].

When bullets are flying stably and ricochet on a surface, only one mark is produced. In contrast yawing bullets can produce a double mark if the angle of incidence is sufficiently small (less than or equal to 5 degrees). Distances up to 15 cm were seen between the two marks.

Compound action potentials in the peripheral nerve induced by shock-waves.

Projectiles hitting the human body cause shock waves spreading throughout the tissue. To verify a presumed interaction between these shockwaves and nervous tissue electrophysiological experiments have been performed showing the following results: 1. Compound action potentials (CAPs) are provoked in the peripheral nerves by the shockwaves. 2. The amplitude of the CAPs correspond to the magnitude of the shockwaves. 3. There is no electrical activity in the peripheral nerves below a certain threshold pressure. 4. "Saturation effect" is occurring beyond a certain pressure limit.

Shockwave-induced compound action potentials in the peripheral nerve.

To verify a presumed interaction between shockwaves arisen by impacts of high velocity projectiles and nervous tissue an electrophysiological experiment is performed with the following results: In peripheral nerves regular compound action potentials (CAPs) are provoked by shockwaves the amplitudes of which are increased corresponding to the pressure intensity of the shockwaves. The nerve shows no electrical activity below a certain pressure threshold (0.75 bar). Saturation of the CAP amplitude occurs beyond a pressure limit of 8 bar.

[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.
