Bullet stop and containment chamber with airborne contaminant removal

A bullet stop and containment chamber for stopping the forward momentum of projectiles on a generally horizontal zone of projectile travel and for containing and removing contaminants, said bullet stop and containment chamber comprising:

• a channel to guide projectiles from a first opening to a second opening, said first opening having a greater area than said second opening;
• a chamber defined at a chamber perimeter by at least two planar impact plates to arrest the inertial momentum of bullets and resulting fragments thereof and a planar terminal impact plate, said chamber further defined at the sides by first and second side plates;
• said chamber further having an ingress complementary and adjacent to the second opening of the channel and an egress for the gravitational discharge of projectiles whose inertial momentum has been arrested within the chamber;
• a fan in pneumatic connection with the chamber wherein said fan exerts an air pressure within the chamber which is less than that outside the chamber and wherein said fan removes a volume of air from the chamber;
• and,
• at least one duct in pneumatic connection with the chamber, wherein said at least one duct transports air away from the chamber.
