JC;
I have no problem at all with recognizing & supporting "Facts" which put down old wives tales. Your reasoning on the max pressure occuring in the chamber was totally logical & supported by facts. One can also recall when Bell reported on blowing up the Parker Damascus @ a pressure of around 30K psi, it blew in the chamber area where it was "Thick", not down the bbl where it was "Thin". Again obivious that max pressure did not carry down the bbl to any extent, as does the illustration you just posted. I do recall this incident being reported here on the BBS.
