Go ahead and buy a reloading manual first, you'll need it anyway, and study the steps to proper reloading. It'll explain the equipment needed, thesteps involved and the safety measures that need to be heeded. Nosler, Hornady, Sierra, Barnes, Lyman and some other companies put out some excellent reloading manuals. When I decided to get started about 5 or 6 years ago I didn't know anyone who reloaded, so I learned everything from the manuals and from asking questions on internet sites like this.

As stated above, the RCBS Rockchucker kit is probably a good place to start as far as equipment is concerned. It won't have everything you need, but it will have most of it.
