Well, I'm feeling vindicated. Been sayin' for years that the only reliable "pressure sign" is the bullet. As in how fast it's going. If yur gittin' much more speed than the manuals or QuickLOAD say you should be getting with safe pressures, you ain't got no safe pressure. In the same barrel length!
I'm not the only one. At least one other posted a similar idea (though in a question as I recall) above.
"Oh goodie, MY gun gets more velocity than yours without any pressure signs!" is the mark of a person ignoring the most important pressure sign of them all.
As wisely noted above, those signs of brass failure all appear well outside of safe/spec pressures.
