Here's a checklist I've seen on the internet.     http://thegunwiki.com/Gunwiki/RefReloadingStartup    Everybody should have a Lee hand press and the appropriate dies at a bare minimum. If you get into progressive machines though, you need to go Dillon or go back to single stage. A machine that breaks a part once every few months is going to be useless in short order post-SHTF.    By the way - decapping pins. Everyone SHOULD keep a good supply of those, as they do break fairly readily.
