Abstract: A range backstop assembly having a container with an opening typically closed by a rubber sheet and serving for projectile entry. The container is filled with a particulate flowable granulate material which slows down the entering projectiles. An anti-adhesion medium is further interspersed between the particles of the granulate material to prevent adhesion of the granulate material in the presence of heat generated by the entering projectiles.

Abstract: The invention relates to a backstop assembly comprising a container (1, 1', 1", 1'") having an opening (11, 11', 11", 11"') covered up by a medium (2) and serving as a projectile entry opening, said container containing a particulate flowable granulate (3) as a medium for slowing down projectiles.

Abstract: A backstop frame for intercepting projectiles is disclosed as including a holding plate having a series of parallel slots in which a series of lamellas are mounted, fasteners, secured the plate to a supporting structure and connectors join the lamellas to the plate.

Abstract: A projectile backstop assembly for decelerating projectiles is disclosed as including a container filled with a liquid for decelerating a projectile, an inlet opening in said container, an elongated sheet of material sealing the inlet opening and a pressure applying frame for pressing the material against the inlet opening, and an advancing mechanism for advancing the elongated sheet of material and thereby replace the pierced part of the sheet with an adjacent unpierced part.

Abstract: A firing range assembly includes a transportable container which encloses a firing range. The assembly further includes a ventilating system for ventilating the firing range. Each wall of the container is provided with a lining which functions to: (i) resist penetration by projectiles; and (ii) inhibit rebounding of projectiles.

Abstract: A target back-stop behind a target area with lamellar rows of lamellae mounted at a distance from one another while the lamellae of a front row of lamellae form a predetermined angle .alpha..sub.1 with the normal of the target area, and while the lamellae of a rear row of lamellae form, in the opposite direction, a predetermined angle .alpha..sub.2 to the normal of the target area. A front end of one lamella of the rear row of lamellae borders on the rear end of one lamella of the front row of lamellae, so that channels will be formed that zigzag between the lamellae, and in which projectiles of widely varying caliber will shuttle to and fro and, in that way, will be braked.
