I was wondering if there is a reference to what I will call "the strength or power of" (since I don't know whether that is brisance or something else) primers that would indicate which would increase pressure significantly? As an example, let's say a Hodgdon published load reference specifies CCI 550 small pistol magnum primers (SPM) and the local gun store is out of CCIs but has Winchester SPMs or Federal SPMs. Does a prudent reloader (someone who wants to keep at or below maximum pressures) wait until the CCIs are available, or substitute brands and then use the chronograph (velocity) to see if velocities are comparable?
Short version: Is there a chart for primers that goes "warmer to hotter" like there is for powders (slower to faster)?
