That's a good looking site there JJ. I didn't know anything about that one. I almost ALWAYS three or four reloading manuals and lay them out on the floor, each opened to the caliber I'm loading. I'll them compare the data and come up with a starting point. I'll ALWAYS pick the Sierra manual as one of those, then the Hornady, Accurate Arms, Nosler, or Speer. I'll also compare current editions with the previous editions..
