They aren't out of battery discharges. The cases fail because the chamber is not supported well. I cringe whenever one of those facebook boomers who shoots 3 boxes of ammo a year say the p320's fire out of battery. It's not possible with the new disconnector design.
Don't combine the fastest powder AND CBC, PPU or Tulammo brass and it will be fine. Ive experienced the bulges and a blowout or 2 but its not a big deal to load around.
The most popular 9mm powder where I live is too fast for the x5 when using the cases I mention above. It is AP50 and APS450, highlighted in the powder equivalent attachment below. Use a slower powder or sort your brass to exclude those cases and it is fine. ps I use CBC and PPU brass in 9 major in an STI with no problems.
