[QUOTE="Autorotate, post: 395359, member: 8073"] QL sees the Case weighing factor is an "efficiency" factor, specifically a relationship between case capacity and bore diameter. .40 is a good place to start for the 338 Edge, and a 300 RUM Improved seemed to work with .36 with most loads/powders. I would look at your case and compare it's relationship to one of those as a benchmark, and then adjust to start. Lower case weighing factor number, equals less total pressure, but more velocity with a given powder charge/bullet weight. Higher case weighing factor number, equals more total pressure, but less velocity.... Start pressure numbers are just like you'd think.... Higher start pressure, more total pressure and more velocity for a given scenario. Lower start pressure, less pressure and less velocity for a given scenario. gun) [/QUOTE]
