OK, somebody is going to have to explain this to me, as I'm way too dumb to figure it out for myself.

When I load, it seems to me that the most time consuming part of the process is case prep. I tumble my fired cases, inspect them for damage, lube, resize, wipe clean, clean primer pockets, trim (my Giraud trims and chamfers in the same operation), expand the case mouth if applicable, then prime. All that is left for me to do then is to charge the case with powder, seat the bullet, and crimp, if that operation is prudent. I can see the usefulness of an automatic press when one loads new brass but after a couple of firings problems would occur - would they not?

By loading in a step-by-step operation, I can wipe lube off bottleneck cases before the machine indexes them to the next station. I can clean primer pockets after the sizing operation. When I seat primers as a separate operation, I can tell if the primer pocket has expanded beyond useful limitations. I can check for cracks occurring around the mouth of the case after I run it through the expanding die. In short I have good quality control at every step of the loading operation.

Every time I have considered the purchase of an automatic system, I consider these things and go back to my single stage press. When loading pistol ammo I could certainly speed up the process with a Redding turret press, but with regards to the auto-presses, I don't want to loose the quality control that the step-by-step operation affords me.

Yet folks are flocking to the Dillons - even some match shooters. So, how about some of you Dillon guys filling me in. Are you using the automatic presses for only 3 operations, charging the case with powder, seating the bullet, and crimping? What am I missing, besides a couple of thousand rounds an hour?
 
Resizing, seaing the primer, belling the case mouth (if required), charging with powder, seating the bullet, crimping the bullet. All done on the press. Trimming, cleaning, sorting, weighing, inspecting is all done earlier. But if you do enough prep work, you can run your progressive for quite a while before you have to prep again. For example, I shoot a lot of 308 (not as much as when they let us take machineguns to the range, but still a lot). I have the brass segregated into various lots, and just load them 500 at a time or so. - dan
 
It'll take more then that to convince me....i load 100 at a time, in groups of 10 or 12, each group has either, a diff. type/charge of powder and/or a diff. bullet and/or diff. seating depth and/or a diff. primer, progressive my as%!!
 
Ahh, I thought because so much was being done with each cycle of the handle there wouldn't be much sensation when seating the primer. I'll talk myself into one of these yet.

You can feel it, as it is the only part that is done on the "down stroke. When loading, flaring, powder drop, seating, crimping is all done on the "up" stroke. Not hard to feel a tight/loose pocket at all, as it is kept seperate from the other stages. Cheers!

Correct for the Dillon 650 and Hornady LNL AP - not correct for the Lee Loadmaster (everything happens on the ram upstroke). It's one of the reasons that the Loadmaster is not suited to precision loading of rifle cartridges.
 
I agree with the stuff mentioned above, my rcbs pro 2000 seats primers on the down stroke aswell.

I would say my ammo might suffer a bit, as I don't clean primer pockets much anymore, maybe when they stretch enough to trim. However I feel that shooting twice as much ammo because it's already loaded will do more for my shooting then a clean primer pocket ever would.
