I don't have hands on experience, but I have been researching it. The tool has three dies, one is just a die that you drop the case in and it aligns it with the "post" on the shell holder, the second is the actual swage die, and the last "picks" the case off of the shell plate and holds it until the NEXT case dislodges it and it falls out.
I saw a video on YouTube where a rather enterprising individual cut a slot in the tube of his case feeder about 1/3 the way up, and added a lever arm to the case sliding mechanism that would "poke" the cases out of the feed tube, flipping them upside down as they did so, and then sliding them down a chute made up of a flexible funnel.
I can't seem to find the video now, but I thought it was genius and wish there had been a better look at it.
