22PPC by another name ?
I'm not an expert buy presumably any small differences would depend on the brass you can obtain and the action you put it in, rather than the cartridge designation.
There is data for 22PPC and 6.5 grendel in the ADI powders manual. We mostly use the online manual but a paper one does exist so ring around and see if you can get one. Someone here could advise where to get one.
Theres a whole forum board on grendel reloading at 65grendel.com and also two paper books available but you could struggle to get around the site on dial up.
