The shooting station 12 may include one or more of a firing position 18 and a 30 shooting booth 20 that may optionally include a weapon rest 24 and or a lane divider 22.

(12) FIG. 3A shows a shooting station with one embodiment of a funnel 26 for directing a projectile into a fluid lubricated deceleration trap chamber unit 82. The funnel generally includes an upper panel 29 and a lower panel 27. The upper panel positioned to define an acute angle b above horizontal h and the lower panel positioned to define an acute angle c below horizontal h. In particular examples, the lower panel 27 may be a dry impact panel 200.

(13) Referring to FIGS. 3A and 3B, embodiments of the fluid lubricated deceleration trap chamber unit 82 generally includes a substantially cylindrical chamber 30 with at least one end plate 8. In particular examples, a wet shooting range 80 may include at least two deceleration trap chamber units 82 attached with end plates 8. The chamber 30 may include any of the elements and features shown and described herein, and as shown in FIG. 3A, the chamber 30 has the rearward concave wall 90 with an inner surface 90.1, an outer surface 90.2, and a an upper wall portion 90.9. The chamber also having a forward concave inner wall 92 with an inner surface 92.1, outer surface 92.2, a forward wall upper portion 92.5, a forward wall upper end edge 92.6, a forward wall lower end edge 92.7, and a forward wall lower portion 92.8. Typically, the rearward concave wall 90 has a concave surface 90.3 whereby fluid flow substantially covers the surface. Further, in certain examples the rearward concave wall 90 has a lower portion end edge or end 94 that is spatially offset and separated from end 96 of the forward concave wall 92. As shown, this segmented arrangement may define a splash exit 70, for instance a gravity-fed exit from the chamber 30, and may assist fluid flow along the surfaces. In certain examples, the exit 70 may include a filter system to remove contaminants from the fluid. For instance, the filter system may include a series of weirs to remove heavy particles and/or one, including a plurality, of strainers before any of the fluid is recycled for future lubrication as shown and described herein.

(14) The fluid lubricated deceleration trap chamber unit 82 in each of the projectile trap assemblies may have a common axis a and be substantially perpendicular to the funnel 26, thereby defining a continuous funnel. As shown in FIGS. 3A and 3B, the fluid system having a fluid discharge 84 to coat lower inner surfaces of the chamber 30. For instance, the fluid discharge may wet and lubricate the rearward concave wall 90. The front wall may also be the forward concave wall 92 surfaces to reduce wear at any of the surfaces shown and described herein. Further, the fluid discharge may lubricate the rearward concave wall 90 and a forward concave wall 92 surfaces to reduce a plurality of airborne particles to minimize, or eliminate, environmental impact of the wet shooting range 80.

(15) Referring to FIGS. 3B and 3C, the pressurized fluid containment may comprise the lower panel 27 of the funnel, the forward concave wall 92 of the cylindrical chamber 30, and an end plate 97 with a fitting 99 for connection to a fluid line 99.1. The discharge 84 may comprise the lower panel 27 spaced from the forward concave wall 92 by a gap defined by spacers 99.4 with spray openings 99.6 in between the spacers.

(16) The fluid lubricated deceleration trap chamber unit 82 may include any liquid handling system to provide the lubrication benefits and advantages introduced and illustrated herein. In one example and shown in FIGS. 3A and 3B, the fluid discharge assembly includes at least one pump 101, for pumping fluid to one or a group of adjacent chambers 30. For instance, the pump 101 may drive fluid lubrication to about five or more deceleration trap chambers 30. Further, the fluid system may include a pressurized fluid chamber 100 with the fluid discharge 84, for instance at an upper portion of the fluid deceleration trap chamber to coat interior surfaces. As show in FIG. 3A, a fluid manifold 102 may be in fluid communication with the fluid chamber by a fluid line 104. The fluid discharge assembly may lubricate the inner surfaces of the deceleration trap chamber unit 82 at any suitable volume and at any suitable flow rate. However, Applicants have found unexpected fluid lubrication success when the fluid discharge 84 provides about forty to about fifty gallons per minute, or the like, per about eight foot section chamber 30. Other examples include less than about forty gallons per minute per eight foot section and greater than about fifty gallons per minute per eight foot section. Those of ordinary skill in the art having the benefit of this disclosure will recognize additional fluid flow rates and dimensions for a particular site application.

(17) FIGS. 4 and 5 show perspective views of exemplary embodiments of a series of projectile traps 14, including inner curved surfaces 36 and end plates 8, used in the shooting range of the present inventions. As shown, the end plates 8 on the projectile traps 14 may provide support. In particular, the end plates 8 may provide support at the distal ends of the projectile traps 14.

(18) Certain modifications and improvements may occur to those skilled in the art, upon a reading of the foregoing description. By way of example, while the shooting range shown includes a circular projectile deceleration trap chamber, other types of traps could be used, including, without limitation, the kind having an impact plate design. It should also be apparent that any rounded shape could be used as a projectile trap and the invention is not limited to just circular one sided shapes. Also, the deceleration trap chamber could be made from a series of plates having flat faces, such as shown in U.S. Pat. No. 5,811,718, issued to Bateman. All such modifications and improvements have not been included herein for the sake of conciseness and readability but may properly fall within the scope of the appended claims.
