I haven't had good luck with Bertram brass (I've used .33 WCF, .35 WCF, .38-72 WCF, and .50-110 WCF but never .318 WR) and I would expect Quality Cartridge to have better stuff. The Bertram was very bad about splitting at the neck (.50 EX excluded) even on first firings, and it seemed to be some of the thinnest brass I've ever used.
