If I were you, I wouldn't buy any reloading equipment until you've bought and read a book by the name of "The ABC's of Reloading". Is a wealth of general reloading knowledge, and breaks down pistol, rifle and shotgun reloading step-by-step. It also talks about some of the different equipment you need and what to look for when buying equipment.
This book was the first thing I bought and it was the best thing I ever did.
