    Another way to look at it is that pressure builds up to a peak and then decreases over milliseconds. Over that time the bullet moves forward, exposing more of the chamber and barrel to those higher...

    Cool. If I can just remember where I put the key to my time machine, I'm headed back to 1959 with $60 in cash for one of the larger oak chests. Should have change left over for lunch at the Horn...

    1) Just machine a long bar (say 18") with the dovetail in it. The slice off holders as you need them, salami like, and machine what you need. Not a huge...

    The 8 drawer metal Kennedy is a good choice. The Gerstner oak ones are cool, but very expensive unless the cheaper Chinese-made ones.
