This Lee Turret Kit is all you need to get started and will take care of your needs unless you shoot/reload thousands of rounds a week. Then I'd say the Hornady LNL AP is the way to go. Here's a complete kit, just add dies and you're ready to go. Other items needed are listed as well.
Add this tumber for your brass: http://www.fmreloading.com/Merchant2...se+Preparation
Crushed walnut media can be found at your local pet store, get the smallest particle size possible.
Add this disk kit for rifle if you need it: http://www.fmreloading.com/Merchant2...Category_Code=
Add your 223 dies of preference
Add this scale for ease of use: http://www.amazon.com/American-Weigh...emini+20+scale
Add a digital caliper from Harbor Freight ($10-$12) or a dial caliper from ebay for under $20 and you should be all set and ready to go.
