So I found an interesting thread on another forum talking about a custom BFR in a custom .50 caliber wildcat that is designed for a working pressure of 95k PSI, its a slightly tapered straight walled cartridge, that headspaces off a belt instead of a rim like most revolver cartridges. Would brass still be a viable casing material for pressures that high? Or would you need to make the cases out of a totally different metal? Would there be a metal that could be used in cases for this cartridge that would be re-usable for the common reloader?
Sorry if this thread is in the wrong area.
