I would definately suggest an update to the current edition of the Lyman manual. At least you can cross check your older data. I don't know this for absolute fact but I really doubt any of the current manuals would include data that would be dangerous using any powder that might be reasonably expected to be sitting on someone's shelf(maybe 20+ years old). Improperly stored powder is a whole different ballgame.
I keep current editions of Lyman, Nosler, Hornady, and Hodgdon manuals plus a LEE as reference. Be advised the LEE is NOT actually a generated data manual-it is a compilation of data from "other sources" and as such should NOT be utilized as an only source. The LEE data is not precise and leaves out vital component info.
