+1 on Lyman 49th.
I tend to rely more on current published load data from powder manufacturers but will cross reference them with Lyman 49th.
Here are some powder manufacturers' load data pdfs (I print them out and keep in a binder next to the reloading bench and also keep them on my computer desktop for ready reference use):
