Indoor firing ranges are usually composed of one big concrete room, lined with reinforced baffles along the walls and roof. Ventilation shafts dot the space, constantly sucking out lead particles and smoke from the cartridge primers, bullets and leftovers from previous sessions. The back wall is often a sloping earthen bank with a collector, designed to stop and capture bullets that hits it. Targets can be both stationary, and in more modern facilities, moving. When designed as civilians, targets are usually made out of paper or plastic coreflute and sometimes when used for long-range shooting covered with some canvas on the back.
