I'm not saying I usually load until I start piercing primers then back off. Just that I've always backed off when I'd see cratering. Of anything else I've reloaded for I've never encountered cratering until I was approaching book max.

Worst case scenario I can gather is I'm taking it too seriously and loading lighter than I could so I don't see what being cautious of cratering can hurt. I'm always open to learning something new though. I have no problem admitting I have a lot to learn and appreciate all the help I can get
