If that brass is a must have you could fire form them back with a min load but if you have more than enough brass I wouldn't waist the components. Furthermore, do check your shoulder bump back to make sure your not pushing them back too far. You only need a max of .001 set back for proper clearance. Another thing is make sure your not over lubing your cases as this will cause a build-up and create the same problem.
CC is right you will have to clean that die real good. It don't take a big piece of junk to make a dimple. I use "breaklean" to clean my dies.
