To: Dave Petzal Subject: BANG Dave, Well you asked for it. I hope you find this useful. Thank you for the opportunity. A graphic reminder of the art of home pressure testing. What I see here is typical of a vastly over- pressure round fired in a revolver. The in- line round of ammunition blew out the top of the cylinder, both adjoining chambers, and removed the top strap. Most of the destroyed revolvers I have seen usually have the top strap of the frame still attached at the front, above the barrel, and it is peeled forward. The weakest point of an adjustable sight revolver frame is the back end of the top strap were the rear sight cut is. In this revolver the whole top strap is gone and most of both adjoining chambers. This points to a very strong pressure spike.
