I had hoped that today I would be able to post the detailed pictures of the powder measure spout assemble for 223 Rem but when I started to take pictures of the batch I just picked up, I found that the section beneath the threads that is relief cut so the spout will seat in the toolplate opening had been cut .017 inch over spec. So another trip to the machine shop! Should be a quick correction. Anyway, the picture below should give a idea of the external appearane. The bottom opening extends up far enough so that the top of the cartridge clears within the shellplate at maximum throw. The inside is tapered the same as the cartridge so there is very little play of the cartridge within the powder mearure spout barrel and a good alignment of the internal 3/16 inch diameter spout as it enters the cartridge neck. The 3/16 inch diameter spout is press fitted in and can be drifted out and replaced if a longer or shorted spout is needed. It is set to start dropping powder just as it enters the cartridge neck opening so the cartridge has maximun support to assure alignment. I learned from a earlier protype that a out of alignment cartridge presses the internal spout up, into the powder slide if the error is not caught, and also ruins the tube,but remember the tube is easily replaceable. With the current tapered configuration, I don't think this error can occur.
