Hi,
Until recently, I used the Lee Auto-Prime with the round primer tray for most everything--and that was my vote. I also have one of their earlier hand tools that just does a single primer at a time. It's set up for large size primers to use for short runs of rifle brass now and again leaving the other tool set up for small primers. Life was good: the tool's been kept lubed per instructions, hasn't been used by any 800 lb gorilla types, and it's still chugging along after I dunno how many years.
Then a buddy sent a bunch of LC .223 brass to play with, which had crimped primer pockets. I thought I had them adequately opened up, but my thumb said "Huh, uh!" when I went to prime them. If it makes any difference, the only small rifle primers I could get at the time were Tulas. So I dug out a Lee Ram Prime from a dusty corner of the drawer and tried it for that primer/brass combo. It made short work of getting those primers seated, requiring just a touch of finesse when first pulling the press handle to give everything a chance to get "lined up!"
Since then, I've been using the Ram Prime more and more when I'm not in any particular hurry, which is most of the time when I'm loading these days. I've been happy with it... unlike those little flip-flop thingies that came on both my RCBS presses, plus a couple of others. Those things drive me up a wall.
