If the initial parameter is 0.001, it's basically impossible to improve on that without spending some serious cash on the constants, chamber, die sets and brass.
That's why I said that .0005" is about as good as it gets. But somebody wanted to know how to consistently measure down to one ten thousandth of an inch. In my book it's not practical, and over the top. I can usually hold my cases within a .00075" window without doing too much effort, and that's more than I need to worry about.
