"1. If you want more precise estimates from QL, you have to provide the overflow water capacity, as suggested earlier. Please note that I'm just providing examples of what you could do with QuickLOAD."
How is overflow water capacity obtained? I would think it would be with the water capacity of the case with the bullet installed? I am thinking I would pop the primer and fill a case with the bullet installed using a hypodermic through the primer hole, then compare before and after weights? I have a digital scale with .0005 lb increments or a power scale that measures  to .1 grain.

"2. Shoulder shape/angle has been consistently demonstrated to have negligible effect on pressure with normal loads of conventional components in cases of equal volume."
This means Roy Weatherby was a snake oil sales man? I sorta figured that

"3. Chamber .010" over case body diameter is completely normal. SAAMI minimum cartridge base: .453", maximum chamber base: .464". This has no practical effect on case/chamber adhesion or "bolt thrust"."
Learn something new everyday, thanks. Hope I can remember it all.
