I've been saving multi caliber pistol and rifle brass for awhile. I'd like to start buying reloading equipment and take the plunge. I don't really want to start small with a beginner setup and was thinking about purchasing a Hornady Lock-N-Load AP.
After a 30 year break from shooting, I jumped back in, and the AP is what I went with. I have had no regrets with the purchase.
That said, there are pluses and minuses to progressives and single stage setups:
Progressives are faster. Hands down you can crank out a lot more ammo on a well-setup progressive than you can on a single stage.
Single stages are [generally, and maybe "can be" would be a better term to use] more precise. For precision rifle ammunition, a single stage press, or/and an arbor press would be the way to go. A single stage press is less complex, so troubleshooting loading problems is a lot simpler.
1. I like the idea of wet tumbling with the primer pockets removed so everything looks shiny. Do people run their dirty brass through the automatic case feeder just to remove the primer before tumbling? Doesn't this step also resize the brass? Resizing dirty brass seems wrong to me.
The advantage of wet tumbling is that it gets the entire case clean: outside, inside and primer pocket. For pistol, I don't worry about the pockets - never seen a difference dirty or clean; for rifle, if not wet tumbled, it gets hit with a manual pocket cleaner, which adds, what, maybe 5 seconds per case?
If you want shiny ammo, once loaded, consider a vibratory tumbler. That will clean the outside to like-new appearance, but doesn't do much for the inside or the pocket. No drying involved. Run time can be as short as 30-45minutes depending on cases and media.
Wet tumbling (in my experience) has a run time of a couple to several hours, takes longer to separate media from cases, and has a drying period afterward.
2. Isn't case length trimming, chamfering and deburring done after a clean case is resized? Wouldn't this step be skipped using a progressive press?
First off, it's not something you need to do every time. Usually every 3 to 10 firings will do OK (you can tell by measuring the cases.)
Ideally, you'd trim after sizing, as the case will grow a bit as it's squeezed. Realistically, either way, as the case growth after trimming will not be enough to cause problems. Dillon's higher end presses have a station that can be devoted to trimming (though I'm not sure about chamfering. I don't use Dillon due to cost.) If you're single-stage, it's an added step in the middle.
3. Is case length trimming, chamfering and deburring only practically done on rifle cartridges? Is a single stage press preferred for rifle reloading?
Yes, and Usually.
Most pistol cases don't lengthen. A test of .45ACP running hot loads and a single case showed that the case actually shortened over time, as the head compressed.
Single stage is preferred for rifle due to the greater inherent precision over a progressive.
4. How does one best use a progressive press to include all the important aspects of reloading? In other words, what is your sequence of reloading steps, including brass preparation, so that you can reload efficiently? It seems to me that a progressive press would be best used with all new brass. Can you add the brass preparation step and still use a progressive press well?
In my case, fired pistol brass gets decapped on a single stage press, wet tumbled, dried, then runs through the AP with standard dies.
Precision rifle ammo gets steel-wooled at firing, neck sized and decapped (arbor press), primer pocket cleaned, checked for length and trimmed if necessary, and then is then considered good to go. Loaded on an arbor press.
AR ammo gets roughly the same treatment as pistol ammo, with the added step of measuring the cases for length and trimming/deburring if necessary. Single stage press with conventional dies. I may move this to the progressive press, if I ever get around to futzing with it to get it working smoothly.
