The Firearms Blog found this great deal on the newest edition of Rodney Jame’s ABCs of Reloading in Kindle format. It costs just $2.99 and of course can be run on your PC or some smart phone platforms.
If you don’t have a Kindle you should consider buying one. There are many ebooks available on the cheap and I’ve picked up special interest books (mythology and folklore for example) for free. Yes free. There are also a remarkable number of public domain titles available at little to no course, including old books on hunting and trapping.
