Sounds like an overcharged shell. Soft case metal wouldn't really cause the hard extraction.
Luckily, with magnum cases and powder, it's hard to overcharge it to the point of catastrophic explosion because the case can only hold so much slow burning powder, even with a compressed load. Not saying it can't go overpressure, but there is a bit more wiggle room.
Yeshayahu 9:7 Of the increase of His rule and peace there is no end, upon the throne of David and over His reign, to establish it and sustain it with justice and with righteousness from now on, even forever. The ardour of יהוה of hosts does this.
