Abstract: Apparatus for collecting cartridge cases ejected from an associated firearm, having an action and an elongated barrel having a geometric axis. A container has at least first and second elongated flanges disposed in mutually perpendicular relationship with the first flange disposed in substantially perpendicular relationship to the geometric axis of the barrel. A deflection surface is provided for deflecting ejected cartridge cases. The deflection surface has at least a part which is generally planar and which is disposed in oblique relationship to the first elongated flange. The apparatus includes a structure for removably securing the container to the associated firearm adjacent to the action.
