This might not be a problem, I just might be the lucky one, but I've had my SDB handle break (crack) on me twice.
I usually use a spray case lube and have annealed by brass.
Right now loading .45 Colt rounds.
First time it was .38 Sp cases.
.
Each time they sent an up-graded replacement
.
Granted it has only happened twice but just wondering if others have had this happen to them
