FWIW, Black Hills does non destructive testing/examination (NDE) of all the cases they use for remanufactured ammo. Any cases showing flaws become scrap.
If the defective round was .40 with 180 gr bullet, the cause could have been bullet setback during the feed cycle resulting in over pressure. This is not unknown with the .40/180 in new ammo that's been repeatedly chambered.
