1. In a bullet trap for catching and deenergizing a bullet fired along a substantially horizontal path of flight from a firearm, which trap includes a first pair of spaced flat plates located on opposite sides of the path of flight of the bullet and a second pair of spaced flat plates arranged transverse to said first plates on opposite sides of the flight path of the bullet, with said plates defining the respective sides of a passageway having at its front end an entrance opening and at its rear end a throat through which the bullet can pass, and a spent bullet decelerating and energy-dissipating chamber the circumferential boundary wall of which is of generally spiral configuration and the opposite end walls of which are constituted by portions of said second plates, with said passageway communicating with said chamber substantially tangentially of the latter through said throat;

  • the improvement comprising that;

    spray nozzle means are provided within said chamber for spraying against said circumferential boundary wall of the latter a liquid lubricating fluid for reducing frictional contact between said circumferential boundary wall and any bullets traveling along the same, and the quantity of said liquid lubricating fluid is sufficient to engulf and flush away any lead dust generated by the travel of said bullets along said circumferential boundary wall as well as spent bullets, fragments thereof, shells and casings.
