I have had exactly 8 cases that split at the case mouth in the past 4 years. I quit counting how many times that they have been reloaded. I always come home with more brass than I left the house with.


The ones that wear out will split at the case mouth when you are expanding them. If that happens. Skip seating a bullet. Just run it into the seater die to remove the flare. Then decap the primer in the sizing die, and then reseat it into a newer case. Toss the split one into a scrap can.
