all the above are good. i would also look for some of the older reloading books. look for the ones made in the 1970's and 1980 time frame. they have some good info and reload data.
While the old manuals are good primers on the basics, many of the powders listed are no longer available, have been renamed or have been changed/improved and the loading data is no longer accurate. In many cases, charge weight recommendations have been changed. Additionally, there are many new powders available that are not covered in the old books.
For actual loads, the most recent manuals are preferred. At an average of $25, having one or two are not out of reach for any hand loader.
At the very least, for current data, the on line manual from Hodgden is a great starting point. It covers Hodgden, IMR and Winchester powders with lots of choices per bullet weight.
