Abstract
A bullet stop and containment chamber for stopping the forward momentum of projectiles traveling in a generally horizontal zone of projectile travel and for containing the projectiles and fragments thereof. The bullet enters the chamber in which the inertial momentum of the bullet is arrested resulting in airborne particulate matter, bullets and fragments of bullets. The bullets and fragments settle out by gravity and the particulate matter are removed by a negative air pressure exerted on the chamber by means of a fan and ducting. The particulate matter is removed from the air by filtration means and the air is exhausted. The fragments and bullets drop from an egress in the bottom of the chamber into a removeably attached canister which is sealed and used to transport the emissions to recycling or disposal.
