In looking into your request, the factory Hornady bin bracket could be duplicated to hold a 2nd tray, but the cost to manufacture that busy lil bracket (Especially the one for the casefeeder)would probably outweigh the demand. However, not being the type to let a request go unanswered, please have a look below.
By modifying the pivot point bracket on the double bullet tray system, you can now flip the bracket upside down and drop the bullet tray all the way down. The end result is the bottom of the bullet tray can be swung over the finished cartridge tray. It doesn't interfere with output and when the output bin is full, just swing the bullet tray away or slide it out from under the bullet tray. Thoughts?
