Sorry to hear that , it could be how you prepping your brass or what and how much powder your using . A few seasons back I used the same 30 cases of Federal brass , when one showed any sign of breaking down I dumped the whole lot , after the 25th time I saw a small crack at the case mouth . I do use the expander ball , full size to .001 - .002 , trim after every firing , I don't annealing my brass and bottom all my primers . I'm not loading hot that may be the reason.
