Based on the recommendation of this page:

I'm looking at the following dies at Midway USA:

If I need to form my own brass, what else shall I need? I would be using either fired or unfired .223/5.56 brass.
Also, what are good sources of 30-221 brass? I would consider forming my own as something I would rather not do if I can buy it. Ideally I would like to run the brass through the dies just like I do for .223 or any other rifle caliber. I am still using a Rock Chucker. Someday I'll upgrade. But not today.
I don't have the barrel yet (it will be made for an AR upper). So I can have the chamber reamed for the dies rather than the other way around.
Thank you.
