2-piper,

Thank you for sharing your 55 years of experience. By what you state it seems that 1000-2000 psi +/- does not matter when a barrel resists to 18k psi without obvious damage and it blows up at 30K psi.

Revdocdrew, thank you for the links provided. Interesting reactions, most of them maybe too enthusiastic based on only two guns trial from 2005.

PeteM,

This is what I am surprised about. The fact that there have been so many guns built over a long period of time, yet no gathered info about safety of their use. We have the numbers and the time period.
I understand that 15 guns may not be a large enough sample to draw a conclusion. How should a study be designed to render valuable, statistically significant data? Is there a place where gun accidents are recorded?
