Gunpowder is a funny thing:
Black powder will burn and build up pressure to a point (@3700bar~53.7kpsi) and then nothing much more happens.
Smokeless on the other hand will readily push 180kpsi given the posibillity.
Wich pretty much mean that you walk a razors edge when reloading modern powders.
This is a standard 45 ACP low pressure load with a bullet set back @1/4" and ended in the 176kpsi range give or take:
Oh, and the good old Kongsberg Colt needed a new barrel and it up and running happy again. And i learned to crimp my bullets in place!
