Over your guys' entire reloading lifetime, have there ever been some major (potential or actual) mistakes that made you change how you do things? Ie, I almost ****ed up X really bad, so from now on I ALWAYS do Y.
If so, can you tell me not just what the potential mistake was, but HOW and WHAT you changed your process to acommodate it not happening again?
After doing this, I see the BIGGEST thing is to just be extremely deliberate and aware. Double and triple check things.
I can tell the biggest risk will be getting comfortable... not necessarily complacent (I am not one to get more sloppy as I get more comfortable), but rather comfortable in that the thought to triple check something might not even come up because you feel more confident and "safer" in your process.
As a basic example, I had small primers on the bench. When I went to reload them a day later, I just grabbed the box and started loading them, sort of innately trusting me putting them on the bench yesterday. It occured to me as I was loading them that I never explicitly checked the box a second time. Small little things like this I suspect are what bites a person doing this... and really one must form some kind of rules or processes such that it "guards" against small slips of the mind, or (even brief) lapses of mental laziness. Kind of like 1 powder on bench at once rule, etc.
