When I first read your title I mistakenly thought you meant the first generation of Lee priming tool, the one-at-a-time version. I have a half dozen or so of them and it is just about my favorite design for priming pistol class cartridges. I keep one set up all the time for the 32 S&W family of cases, for instance.

I used the round reservoir Auto Prime a few times, because Dad had one, but I was really not enamored with it... I really can’t see what all the excitement was about. But then again, I also like to use the Lyman 310 tool for priming as well the Pope style, both of which lack the multi-primer reservoir, so there may be a pattern here.
