Add another big fan of the RCBS bench mounted auto priming tool to the list ... I've used them all, still do, but my favorite is the RCBS auto bench primer. I have an auto prime attached to one of my Rock Chuckers and an auto prime that I really like attached to my Redding T7 (of course the 650 has a priming station but that doesn't count with what we're talking about here.)
Now, with that said, there is a caveat in the form of a learning curve when it comes to the RCBS auto bench priming tool and it is this ... take heed, pay close attention.
When you first get it you'll soon find yourself going fast. It's not unheard-of to seat 50-60 primers a minute once you get in a groove and get the feel for the thing but ... beware.
So here is one very important thing I suggest you do immediately when you first get your RCBS auto bench prime. You cushion the pivot arm between the seating pistol and the drop tube so the tube does not bounce on the backstroke and cause a primer to get sideways. It's easy to do when you're new and moving fast and next thing you know you've rammed a primer home sideways and now its stuck in the case shell holder and there is no banging that thing outta there ... it almost always has to be drilled-out.
Take the bounce out of the primer tube on the backstroke and your problems are solved, move as fast as you want-to once you get the feel of the thing. It's a great priming tool. I have one permanently installed on a RCBS accessory plate and that is installed on a custom Inline Fabrication quick change plate ... that's how much I depend upon and put to use that bench auto primer ... I've actually got about $200 total in the setup and it was worth every penny.
9mm or 5.56 ... I can consistently prime 500 cases of either one easily (most of my range runs are done in 500 count lots) in under 20 minutes if I already have my tubes loaded with primers which - btw - is another plus. That being that if you already have spare RCBS autoprime tubes for your Rock Chucker or Rebel or whatever, those will also work in the bench prime system.
