ofd343,
I'd recommend something like The ABCs of Reloading. If you can find one of the original printings done by Dean Grennell, they were very good. Informative, basic and complete. The suggestion of the reloading manuals is likewise a good place to start. While I really like the books that Glen has done, they're definately not a place to start. Or the books that Dave Brennan edited, either. Either of these will simply give you more information than you really want right now, and will overwhelm you at this point with a ton of details you won't have the experience to make use of just yet. Great books, but save 'em for later.
