Pretty much all the bullet makers have good manuals. I have Lyman, Sierra, Nosler, Barnes, Lyman cast, and hodgdon(both yearly and the old #26). If I were locked to one or two I'd go Sierra and Nosler. You can always get info from powder makers on the web too.
When I buy powder at the gun show they are almost always giving away small loading books from the powder makers. The gun shows down here have a booth where I can buy powder cheap. I got Varget and 2000 mr for $26.00 per pound total each , out the door .
