A device for organizing, conveying and placing ammunition cases consists of a module with an array of funnels on the top face. When cases are poured onto the top face the funnels direct the cases into bores below, generally with the heavy end (rim and extractor groove end) down. Edges of apertures in a plate which slides in a slot in the bottom of the module engage the extractor groove in each case and secure the cases between the plate and module with spring pressure. After securing the cases they may be conveyed to another location at which point the spring may be compressed to release the cases leaving them arranged neatly. A tray is used to contain and interface with a plurality of modules. By adjusting wedges in the tray, the plates in the module assemblies engaged by the wedges are caused to operate as described previously.
