I like the Sierra manual a lot for jacketed as it has a lot of powders listed, also Nosler, and the Lyman for lead bullets.

Because HP are blunt nose they are usually seated deeper into the case so the bullet tip does not jamb in the barrel chamber/throat. If you seat a FMJ out near max COL you should be able to use any data for same weight HP. Just don't seat the FMJ to the shorter COL listed for the HP as FMJ often are longer and this would cause them to be seated deeper in the case and increase pressures.
