I have worked up 45acp in a rifle until the primer fell out.
That is way up there ~ 60 kpsi.

But in a semi auto pistol with a reasonable slide mass and a reasonable recoil spring force, the recoil should stop the work up before 20 kpsi.

Before 20kpsi is reached, the cases should be landing at least 5 feet away and the slide should start hammering the frame.

20 kpsi pressure, there is nothing to see.

Are we a nation of competing ideas, or a nation of forced conformity of thought?
