Those cases go to the scrap dealer. I would have the rifle bolt face checked as the gases may well have cut into the bolt face; there may also already be something wrong with it. Headspace was mentioned and that should also be checked; try gradually sizing a case to find the point at which the bolt will close on the sized case, then measure the neck and compare to the cases you have already sized. Just some thoughts...
