lyman's 48th is at the top of my list. I still go to the powder mfg web site before loading a new powder or changing a load on a powder I have used before. I have on the shelf right now Sierra, Lyman ( both metallic and shotshell), Lee's and an older Hodgon's. Hodgon no longer publishes a hard bound book but instead went to an annual. The powder Mfg put out little paperbacks on their powders that are usually available for free whereever that powder is sold. I will be picking up Nosler soon.
