But as for the Dillon, all I know is it uses a vertical drop tube like the LNL and then some type of rotating plate.
I was going to go take a picture of mine and post it, then I remembered that I accidentally left my digital camera outside through the two largest thunderstorms of the year... I guess I'll just try to describe it verbally.
The 650 does use a disc, about 2 inches in diameter, with primer-size holes all around the outside. (there's a separate disc for large and small primers) Assuming you're standing directly in front of your bench looking down on the primer disc, the primer tube is at 3 o' clock, station 2 (where the cases are primed) is at 9 o' clock, and there's a small plastic ramp under the primer disc at around 6 o' clock. A primer drops from the tube down into one of the cutouts in the disc. Every time the ram is raised, the primer disc rotates by one cutout via a tab that hooks into a primer hole in the 6 o'clock location, pulls back, and advances to the next hole. There is also a manual pull tab attached to this so you can cycle the primer disc with your finger. When a primer makes its way over to 9 o'clock to be put into a case (there are 7 or 8 primer holes between 3 o'clock and 9 o'clock), the primer disc becomes the meat in a sandwich, the bread of which is the shell plate and the primer ram. At this point, the primer is resting directly on top of the ram. On the forward stroke of the handle, the primer ram comes up, shoves the primer into the case, and the primer disc cycles forward again when the handle is pulled down.
I know that seems like a lot of words, but the priming system is actually incredibly simple. I really wish I could post a good picture... maybe I can borrow a digital camera from a friend.
