Thanks for all the info and I did get signed up for the Metallic Cartridge Reloading class.
The course material was prepared by a group that consisted of experts from a number of reloading component and equipment manufacturers. It goes into more of the theory and safety information than any other resource I know.
In the classes that I teach, we run a lab in the afternoon where we actually load some rounds, and then take them out to the club range to chronograph them. This helps introduce you to how a press feels when it's working properly, and how to sense when things go wrong.
I'm very conservative in my approach to reloading. After the class, you'll know why...
BTW, get a copy of George Nonte's book on "Modern Handloading". He goes into theory and will help you develop a perspective on the craft. It's an older book and I found a used copy.
