Could be the type of lube and no vent space? I was using some RCBS lube (very thick) and it had to be used extremely sparingly, even then it often caused dimples. Then switched to the hornady wipe on stuff (looks like lard) and very rarely there is dimpling.

Good idea about cleaning the dies. It's dimpling because there is air trapped between the case and the die and it has no place to go because the lube is sealing too good. Don't full length size if you don't have to as you will just be work hardening the case, can you get away with neck sizing only?
