Re: Damaged Cases
I periodically swipe the inside of the die body with a q-tip, pulls out a lot of gunk. I wonder if blasting the dies out with Rem-Oil or Birchwood is a good idea. Like everyone said, those cases are fine, dents will iron out when firing. Go easy on the lube, and be wary of spray-on lubes. A lot of cases have been stuck from improper lubrication. If it starts to feel tight, STOP! Back out, re-lube.
ETA: from the pics it seems like you aren't tumbling your brass. Not that its necessary, but it removes the majority of grit and dirt off the cases..if you are sizing without at least wiping them down thoroughly you are sure to introduce foreign particles to your die bodies and they will accelerate wear through abrasive action on both your dies and your brass. Keep em clean and slick..
