Hello,
I am able to compute the effects of most of the variables that go into producing accurate loads, but I'm coming up short on hard data about case volume. There are innumerable threads with uncorroborated opinions about the importance of case volume (and flash hole prep, and neck turning, etc.), but I can't find a single instance of someone isolating the case volume variable and producing empirical data.
Obviously the best thing for any particular load is to do is sort my cases, charge with the best precision I can muster, and chronograph them. However, I shoot a few calibers, and develop loads for a bunch of friends, so that's not an experiment I want to repeat over and over until I've picked out how the results correspond to bullet weight, powder chosen, and nominal capacity. If there's work by German Salazar or Bryan Litz or someone similarly dedicated that provides a more general guideline for case capacity vs velocity variation, I'd love to read it.
Does anyone know of any such work?
Thanks!
