I have a Browning a bolt in 300wsm that I load for.Today I shot a few rounds and noticed that the shoulder and neck was split in three places on one of the cases. These are handloads.The loads are Winn cases fl sized,55.5gr of. Varget,lr primer and a 165 gr Hornady interlock loaded to spec.Could this have been just a bad case?
EDIT! 55.5 gr of varget.
