I tell you I scared the living daylights out of myself with this.
That's the best part of the story.
We all, occasionally, need a good reminder of why we have so many safety checks in our process. (Or a reason to implement them, for the people that think they're infallible.)
Other reloaders in my family are constantly saying that my reloads are likely (we've never tested them) to be more consistent, more accurate, more predictable, and less likely to cause a catastrophic failure, than their own. ...But it doesn't instill confidence in me. Instead, it makes me become even more anal retentive, and apply even more safety checks in my process. It may happen, some day; but I plan to postpone that absolution, indefinitely...
