I like my Lyman manual also, but the most versatile I would have to say is the Loadbooks for each individual caliber. There available in Midway, Cabelas, Gander Mtn., etc. They have copies of each specific caliber from all the big manuals and manufacturors compiled into one. I bought one for each of the calibers I reload frequently for. It gives you a chance to compare different data from all the big names in one book. Its real handy.
