I'm pretty much a newbie to reloading, but a co-worker of mine recently cleaned out a storage unit he had and dug out a Dillon RL550 press with other accessories (brass tumbler, 5 lbs walnut shell media, Hornady powder scale) and just gave them to me, saying he hadn't used them in 15 years or so, doesn't have any guns anymore. Tried paying him but he wouldn't take it. So that sparked my interest in reloading... I've been researching practically endlessly, picked up a couple die sets, couple books and manuals. My girlfriend even got me a gift card to Gander Mountain to help get me started with reloading. I'll probably be loading for .308 (my SOCOM), .45 ACP (the 1911's), .40 S&W (brothers gun), and 6.5x55 Swedish (my Mauser). I know I'll need to get caliber conversions for the press, as well as materials (powder, bullets, etc.), micrometer, case trimmer... anything else I'm overlooking?
