I had a partial case head separation using a 1.8oz buffer

This last paragraph supports the partial extraction model, no others.

It supports everything I've stated. We are going in circles. If the case didn't rupture at peak, it will never rupture in battery afterwards.

By the science, there is a specific peak force that ruptures an alloy at a failure node. If that same exact brass has not ruptured by that pressure, then it will NEVER rupture at a pressure lower than that. The reason is that the brass already withstood deformation at a higher pressure. It's not all of a sudden going to get weaker after that. The forces to deform it are simply lower than that of rupturing it. As proven by it NOT rupturing at peak.

Edit: Ok goodnight for real!
