If it were me I'd forget the BPI manuals. Just about everything in them is for the products they sell [ which is ok I suppose, but not really informative ] and second I believe they use computer generated formulas, not real testing.
I second what Bill said. Just get for free the powder companies reloading booklets. Look em up on the internet and give them a call or email and they'll send you one.
