ABSTRACT:
A bullet trap for a horizontally fired bullet includes a passageway bounded by upper and lower flat plates which may be inclined to the horizontal at an angle of between 0.degree. and 7.degree.. The passageway has an entrance opening and a shallow exit opening or throat, and a generally spiral-walled spent bullet energy-dissipating chamber having a horizontal axis communicates substantially tangentially with the passageway through the throat. A white water lubricant is sprayed against the circumferential boundary wall of the chamber and engulfs any lead dust, spent bullets, and other particles, the lubricant then flowing down through the throat into the passageway and along the lower plate into a collecting vessel, flushing the lead dust, spent bullets, etc. into the vessel without possibility of escape into the environment. The self-cleaned lubricant is continuously recirculated from the collecting vessel to the spray head in the chamber.
