Abstract: A dual chamber bullet trap has a housing divided into two chambers by an impact plate that extends rearwardly and downwardly from the front to the rear of the trap. In one embodiment the impact plate is fixedly sealed to the housing thus defining a lower-forward chamber below the plate partially filled with water for receiving bullets deflected off the plate, and a second water filled chamber above the plate for stopping bullets which penetrate the impact plate when it fails due to repeated bullet impacts. When the impact plate fails water drains from the upper chamber indicating failure of the impact plate. In a second embodiment the impact plate is hinged along its front edge to the top-front of the trap and is free to pivot upwardly upon bullet impact to help dissipate bullet energy. The upper chamber contains a fluid filled container behind the pivoting impact plate. When bullets penetrate the impact plate they pierce the container allowing water to drain therefrom to indicate impact plate failure.
