Start with a good manual for metalic reloading and one for shot shell fiirst. Lyman makes a good one for both types of reloading. After you have read the how to section a few times you will get a grasp of the tools you will need. Not to scare you but you will need three presses. They make conversion kits for the shot shell pressses but most people buy a press that's set up for either 12 or 20 GA as it's easier that way. Then the other press is for the metalic cartridges.
