Well I had nothing to do today so I decided to read this and thought I'd toss in my two cents.
We all develop our own routine. I prefer to do large batches, especially case prep, one step at a time. I include a note marking off the steps as I finish them. It may be a while before I do the next step and because of my records I know without a doubt I've completed a step or not. Once I had 1000 30-06 cases I knew I had measured the length on but didn't have a note so I did it again.
I also never touch primers. I started into reloading by loading 8mm mauser. I loaded 10 rounds at the starting load. When I was priming them I touched the primers. I had 1 squib in that batch of 10. I recognized something was off and cleared the bore before firing another round so no harm was done and I learned something and no longer touch primers. Sure it could have been a bad primer but after thousands and thousands of loads I haven't had another squib.
This was briefly mentioned but a paper clip with one end bent can be a very useful tool for inspecting cases. We all (assuming you read your manual) have heard about case heads separating. If running a paperclip inside the cases and tip hangs up on a "ridge" just above the web it's time to retire the case. But it can also hang up on dirt too. Here's a link for more info on it http://www.accurateshooter.com/technical-articles/case-head-separation-cause-diagnosis/
I didn't see this mentioned but I also RE-READ the info in the manuals from time to time. A refresher never hurts and you'll be surprised how often you'll pick up a new tid-bit of info.
I'm a big fan of headspace gauges and have one for every rifle cartridge I load.
Keep your bench clean. Some of the pictures people post of their bench make me cringe. Stacked 3 layers deep of different things seems like a bad idea to me.
I'll also say trust your gut. We all know sometimes there is something telling you that something is not quite right. I've thrown out some brass that despite all my careful inspection and found nothing wrong with my gut was still telling get rid of it. This included a decent size batch of 308 brass. Did I prevent an accident, I'll never know but I felt better by tossing it into the scrap bucket. There was another day I was going to load up a few rounds but I literally dropped everything I touched when I was getting my stuff out and ready to go. I took that as a sign that I wasn't meant to do any loading that day.
Don't reload when you're tired, sick, distracted, mad, ect. Only do it if you can give it your full, undivided attention. Also, once your a have a cold beverage you're done for the day.
I'll say this one separately but don't reload when you are in a hurry. If you are rushing to make ammo the night before a match, hunting trip, range time or whatever the case may be you're asking for trouble. Way to many problem threads start with "I was in a hurry". A little planning can save a lot of problems.
