As everyone has already said, doing some reading is a good first step. I'm not that far ahead of you, I've been doing my studying and my RCBS Rock Chucker kit and the RCBS Accessory kit just arrived a few days ago. I picked mine up from
www.tjgeneralstore.com. They had competetive prices, had the kit in stock (Midway didn't), and I've dealt with them several times and haven't been disappointed. The accessory kit is a good addition, gives you a powder trickler and a dial caliper, as well as a few other odds and ends.
A couple possible additions to your library: Hornady's Handbook of Cartridge Reloading (two volumes) is very good, as is Nosler's Reloading guide 5th edition. If you decide to load Sierra bullets you'll want to pick up their reloading guide. Make certain you get the newest, the 5th edition was just released. You can pass on etting Speer's Reloading Manual if you decide to go with the RCBS Rock Chucker kit, they include a copy. Now I've got two!
You may also want to check into reloading instructors at
www.reload-nrma.com. An instructor in my area has offered to walk me through the setup and first load, to get me started.
