Get one of these. Well worth it if you're gonna keep using military brass. You can work 10 pieces for every one you work with one of those.

Get you a couple of load manuals like a Lyman or a Hornady book. The Lyman will have some reading in the front to tell you about reloading do's and dont's. Just basic knowledge about how it works. Check the NRA page for local reloading instructors and don't be afraid to ask questions.
