Objectives: The two experiments presented were designed to look at the actions of bullets during ricochet events. Shots were fired onto the surface of each of four media. Methodology: This presentation uses high-speed video and still images taken at the Yuma Proving Ground to demonstrate bullet actions following ricochet from 4 different surfaces. The surfaces are concrete, wallboard, steel and asphalt. The cameras used are Redlake HG-100K cameras. One sequence also uses a high-speed Infrared camera by Indigo systems. One of each test will be presented through 3 shots were filmed of each. Results: The presentation will allow the viewer to see for themselves what actions the bullets go through during ricochet. Including but not limited to the Yaw characteristics that occur. Conclusions: As has been noted in literature on the subject bullets ricocheting from softer surfaces tend to go higher. Bullets off of hard surfaces tend to yaw nose down.
