I emailed Mr. Brown and here is his response,

Mr. Phillips,
You are apparently working out of the 1st Edition. You are correct in your assesment of the pressure. The 32,000+ PSI was a typo (should have been 12,000) and has been corrected in the 2nd Edition (the 2nd Edition states "13,000+psi").

I appologize for the confusion. When I had people edit the book, they mostly read for content, gramatical, and spelling errors, no one double checked my math, which as you have discovered, was a problem. Unfortunately, there is an error in the 2nd Edition as well. When I "cut and pasted" trying to correct errors from the 1st Edition, I created an error in the 2nd Edition that was not caught. It has to do with the calculation of the area of the head diameter of the rifle cartridge.

Once again I apologize for the confusion. Good luck with your projects!!

Regards,
W. Ellis Brown
