I still am unclear as to why it would be dangerous to shoot the same bullet, that is operating at the same pressure down a barrel by using a case that is larger.
This is a chamber pressure chart I am using

Maybe I am getting closer to understanding...but I really do want to understand this.
Clearly, chamber pressure taken alone is not something that should be the golden rule of what defines an actions ability. We need to compare apples to apples, case in point, a 45 Colt running at 19,000 cup would not be something even open for discussion.
Bret et al; So larger case head makes the opposite more felt, and creates more stress on the reciever? Why? This is Gunsmithing 101 and I am having fun learning!
