I've always had good luck with Nosler data, their "most accurate" powders are usually a good place to start. Same with Sierra, they have accuracy loads and those are the powders I start with for a given cartridge. Berger and Sierra have some good information in them about more than just load data. Reading the section, some 15+ years ago, about external ballistics in the Sierra manual is what's driven me down this whole rabbit hole. The section in Berger about seating depth tests goes in depth (no pun intended) and is a very helpful process to put into practice. Hornady is another good book with updates and new data every year, it seems, I usually turn to Hornady to get an idea of new powder and cartridge combos. The Lyman book has been very valuable to me loading hard cast bullets for handguns.
I have a lot of different manuals and they seem to all benefit me in some ways that others don't.
