Speaking of temperature sensitive powders

[grayfox]

One thought has occurred to me from time to time on this topic of temp sensitive powder... maybe that sensitivity differs for different cartridges.  And especially the question arises, what about the more, say, efficient cartridge cases.... comes up now because of the powders hornady lists, the ones giving us the MV are ball types like cfe, lever and 2520.  Could it be that cfe is less sensitive for this more efficient case..  might even be true comparing 308 case vs say the creed....  anyway, maybe others have some ideas on this.
