I am starting this somewhat as a complement to Harley45's thread on Water's Method. While thinking about his thread, and Water's Method, I started to wonder if my maximum measurement (which was captured in yellow brass) is even partially applicable to nickel brass (which I mostly use). I just realized that I have NEVER seen a Glocksmile in nickel brass. Have you? I worry because I know nickel brass expands less, and I usually try to compensate by stepping my maximum case expansion down by .001" to stay safe when using nickel. I'm starting to wonder if that is enough. I know I can figure up a baseline pretty easily, because I have a load that will put minor Glocksmiles in yellow brass, but not nickel. So, I guess I need to make a new, nickel baseline with that load. Anyway, has anyone ever seen a nickel Glocksmile?
