For this shot, Sailer clamped a piece of chalk into a drill press and drew rings using a felt pen to add contrast and interest.
He takes the pictures in a dark room positioned about 20cm from the target. The camera is set at a one-second delay giving the photographer enough time to click the camera shutter and fire the gun. The 17,000 volt flash, a homemade set up built on the principle of a Harold Edgerton design, is triggered as the 200 meters a second riffle pellet passes through a laser beam.
