Alliant buying Hercules has definately changed some of the powders such as 2400.
I also suspect that the loading book authors now declare maximum when 1 shot of a 10 shot string reaches the pre-determined pressure limit, instead of the 10 shot average reaching the pressure limit. I don't know how else to explain the large differences in the listed max average pressure between different powders for the same bullet/cartridge in the loading manuals.
