The answer is none. Reloaders cannot get the powders used by the assorted ammo makers. They do not publish what components they use anyway. The manufacturers load for a specific velocity range at SAAMI spec pressures and they don't use the same powders commercially available. Plus, they can use one powder for one lot of ammo and another for the next.
I'm partial to the Lyman manual. It's more versatile than any bullet or powder makers book.
And you'll find IMR4064 is more consistently accurate than 4895. At least in .308. I don't load 8mm.
