Part two in my ongoing series of gun myths, actually just me wondering aloud (in print?).
So I've read it and heard it everywhere: Be careful with rounds that have been (re)chambered but unfired, the bullet setback causes the case pressure to rise to dangerous levels. Usually told in this fashion: "My cousin's nephew's uncle's grandad had a KB due to bullet setback, he almost lost an eye." In researching this myth I found many of the same anecdotes but no documented cases of bullet setback causing a gun to KB, let alone an injury. Anecdotally I've personally fired many cartridges that have been setback to various degrees with no noticeable effect. But I admittedly don't know how to measure case pressures, so I don't really know.
What say you?
