I had the same thing happening with my .243 brass (federal). When I was resizing last night I tried a couple different things and it seems as though you get those dimples when there is excessive lube on the shoulder of the casing. After rolling the cases on the RCBS pad I would just wipe some lube off the shoulder before resizing - did not see any dimples after that.

I threw away the ones that are dimpled, I am testing out new loads so I would like to have as few variables as possible although I can't really see the dimpled cases affecting anything.

Cleaning the die may be a good idea too.
