Please note from previous post " I'm willing to accept blame for reloading error, but can't see how to duplicate the error" KY, Thanks for the note on your experience with the PW. Since you have had this problem also, I can relate to looking at the machine and being puzzled how this happens. I remember you relating the story and your toss off the bridge from the post of a couple years ago. Nice touch.. It's obvious it's a pressure issue, figured it out from the last time this gun incident was posted. Details of gun condition etc was as I saw it. Each gun is an individual in its own, and the Bell trials had guns of poorer condition holding together in high proof loads. As an after incident observation, I thought this gun was strong enough to withstand this overload. But, I'm buying the overloaded shell as the culprit. Being within 8 ft. of the gun when it went off, there was no unusual loadness to the report. Just the sting of the metal fragments was the only difference. Glen said he felt nothing in increased recoil or louder report. Even said he busted the claybird. Wad was found among the others. That's how it was. Randy
