Greetings,
The principal problem I had with Hornet cases years ago were neck cracks from brass that was too hard. In my case this was old brass but it can be caused by too many handloads. Annealing every few loads would help with this. I do this with a candle much to the horror of some Forum members. With the right technique I have had good results from this. With the amount of stretching I would also be concerned with incipient head separation so the cases should be checked with a bent paper clip for a groove on the inside of the case just above the head. These are made more likely by FL sizing with the die down hard on the shell holder. The die needs to be backed out until the cases just chamber freely. None of this stuff is all that difficult but without attention to detail case life for the Hornet can be very short.
Regards Grandpamac.
