The most helpful to me in the last few years has been Sierra's manual. Years ago it might have been Richard Lee's book or before that the Lyman manual. These days I run everything through Quickload ---BUT--- as the Quickload program will tell you over and again, I double check that data against my manuals, mainly the Sierra because it has data for target cartridges that most others, if not all the others do not.

I have had the experience of seeing a load that is stated to be under max pressure on my Quickload screen and seeing that same powder charge as above max in my manual. The manual was right. I had a hard bolt lift nearly a whole grain of powder before the Quickload max was reached.
