[QUOTE="Engineering101, post: 965500, member: 63138"] benchracer One of the things I've figured out about QL is to take advantage of published load data max loads from the various bullet makers handbooks since many of them use pressure barrels, max loads are known to be near max pressure. For example, 62,000 PSI is typical for a 65,00 PSI cartridge. By using the known pressure you can figure out what the WF needs to be. I've also found that WF changes (drops) as you add powder to a case. I have data showing it drop from 0.63 to 0.53 while powder went from 39 to 41 grains in a 260 Rem with 108 grain Scenars. [/QUOTE]
