It was then performed a qualitative testing on animal carcasses and other quantitative testing on ballistic gel; it has come to demonstrate the inadequacy of its point in tissue penetration (compared to Epipaleolithic composite microlithic projectile points and triangular bifacial points of the Old Neolithic).

The qualitative wild game carcasses testing (Roe deer, Fallow deer, Red deer and Wild boars, from 28 to 140 kg body weight) was addressed to bones and joints and the data obtained speak clearly. The surface of the "target" body, except the abdomen, has a bone protection, powerful in the vital area thanks to the rib cage. Out of 102 arrows, with perpendicular trajectory to the surface of the target (characterized by a discrete range of masses, speed and size of the tip) there were only 41 partial penetration (28 of which no more than 2 cm), none of which could even remotely be considered "deadly". The scapula of a 28 kg. Roe deer is never minimally outpenetrated. On the other hand, there have been 33 rebounds and 77 ruptures of the distal end of the shaft with zero penetration (Figure 2). In the latter cases - despite the reinforcing sinew below the interface shaft/point - the wedge effect of the arrowhead caused veritable "explosion" of the shaft. The shots where the spine is hit directly can certainly cause paralysis (and thus facilitate recovery) of the prey, but shall be considered incidental in a hunting event: in these cases the point embed in the bone few mm. The shoots addressed in the thoracic ribs (natural objective of a good bowhunter) have always proved to be ineffective: even if some of these shots have caused the fracture of the rib to the impact, the transverse arrowhead was immediately stuck in the shaft.
