A bullet funnel extending forwardly therefrom. The funnel having a lower panel connecting to the forward concave wall in conjunction with an end plate defines a pressurized fluid containment with discharge outlets directed to the rearward concave wall. All plumbing may be secured below the ramp and forward of the chamber. ## Claims ### Claim 1 A shooting range having a plurality of projectile deceleration trap chamber units with a fluid system, each projectile deceleration trap chamber unit comprising: a forward concave wall and a rearward concave wall defining a chamber, the forward wall having an upper wall end edge and a lower end edge, the rearward concave wall having an upper wall portion and a lower portion end edge, the forward and rearward walls defining an upper bullet entry and a lower slot for de-energized bullets and debris; a funnel positioned at the top of the chamber for guiding bullets into the upper bullet entry, the funnel having an upper panel member and a lower panel at an acute angle below horizontal; the lower panel and forward concave wall having a convergence with respect to one another, a fluid outlet positioned at the convergence and the fluid outlet pointing at the inside surface of the rearward wall, the fluid outlet part of the fluid system further including a pump and a fluid reservoir. ### Claim 2 (depends on 1) The shooting range of claim 1 wherein each fluid outlet of each projectile deceleration trap chamber unit is defined by a plurality of metal spacers serially positioned between the lower panel and the forward concave wall and defining a series of outlets between each two adjacent spacers. ### Claim 3 (depends on 1) The shooting range of claim 1, wherein each fluid outlet of each projectile deceleration trap chamber unit lubricates said concave rear inner wall of said deceleration trap chamber. ### Claim 4 (depends on 3) The shooting range according to claim 3, wherein each forward concave wall of each projectile deceleration trap chamber unit is also lubricated by the fluid system. ### Claim 5 (depends on 1) The shooting range of claim 1, wherein said fluid system discharges about forty to about fifty gallons per minute per eight foot section of deceleration trap chamber. ### Claim 6 (depends on 1) The shooting range of claim 1, wherein each lower slot of each projectile trap chamber unit provides a gravity-fed fluid exit. ### Claim 7 (depends on 1) The shooting range of claim 1, further comprising a plurality of targeting systems and one or more sidewalls. ### Claim 8 (depends on 1) The shooting range of claim 1, further comprising a heating ventilation and air conditioning system. ### Claim 9 (depends on 1) The shooting range of claim 1 further comprising an administrative facility having a safety area where firearms may be inspected and readied. ### Claim 10 A shooting range with a projectile deceleration trap chamber unit with a fluid system, the projectile deceleration trap chamber unit comprising: a substantially cylindrical chamber with a forward wall and a rearward wall, the chamber having a forward facing upper bullet entry and a lower slot for de-energized bullets and debris; a funnel positioned at the upper bullet entry, the funnel having an upper panel and a lower panel, each arranged at an acute angle with respect to horizontal; a fluid system for dispensing fluid into the cylinder at the rearward wall at the upper portion of the cylinder; wherein the lower wall of the funnel of the projectile deceleration trap chamber unit extends towards the forward wall of the chamber and fluid dispensers are positioned between said lower wall and forward wall for dispensing the fluid into the cylinder. ### Claim 11 (depends on 10) The shooting range of claim 10 wherein the lower slot of the projectile deceleration trap chamber unit opens in a downward and rearward direction. ### Claim 12 (depends on 10) The shooting range of claim 10 wherein the forward wall of the projectile deceleration trap chamber unit also has fluid applied. ### Claim 13 (depends on 10) The shooting range of claim 10 wherein the forward wall and the rearward wall of the projectile deceleration trap chamber unit are both lubricated by fluid from the fluid system. ### Claim 14 (depends on 13) The shooting range of claim 13, wherein each the slot of the projectile trap chamber unit provides a gravity-fed fluid exit. ### Claim 15 (depends on 10) The shooting range of claim 10, further comprising a targeting system. ### Claim 16 (depends on 15) The shooting range of claim 15, further comprising a heating ventilation and air conditioning system. ### Claim 17 (depends on 16) The shooting range of claim 16 further comprising an administrative facility having a safety area where firearms may be inspected and readied. ### Claim 18 A shooting range having a plurality of projectile deceleration trap chamber units with a fluid system, each projectile deceleration trap chamber unit comprising: a forward concave wall and a rearward concave wall defining a chamber, the forward wall having an upper wall end edge and a lower end edge, the rearward concave wall having an upper wall portion and a lower portion end edge, the forward and rearward walls defining an upper bullet entry and a lower slot for de-energized bullets and debris; a funnel positioned at the top of the chamber for guiding bullets into the upper bullet entry, the funnel having an upper panel member and a lower panel at an acute angle below horizontal; a fluid outlet positioned at or proximate the top of the chamber for lubricating a rearward concave wall surface of the rearward wall, the fluid outlet part of the fluid system and further including a pump and a fluid reservoir; wherein the fluid outlet of the projectile deceleration trap is positioned between the lower panel member and an upper edge of the forward concave wall.
