PROBLEM TO BE SOLVED: To provide a structure of a firing range capable of easily collecting lead bullets by limiting a fire range, and reducing a space of the fire range. SOLUTION: A bulletproof curtain 5 having strength for enduring impact shock in landing is suspended like flag, honeycomb or hanging curtain from a frame 41 or a joint of a truss-shaped dome framework structure 4 constructed to cover a shot area 2 of a prescribed space in the firing range from its upper portion. The bulletproof curtain 5 instantaneously bends like waves when the flying lead bullet B is collided therewith, and absorbs kinetic energy, thus the lead bullet B fitted to the bulletproof curtain 5 drops on land surface while losing its kinetic energy.
