http://www.natchezss.com/ammo.cfm?category=3 I have ordered quite a bit from Natchezss over the years. Good stuff and good prices. Here is some listings from ammo engine. http://www.ammoengine.com/find/ammo/.223_Remington_5.56x45mm Just type in the caliber. AR15.com also has a ammo page that is supposed to be updated daily. It will show you the cheapest ammo available each day in different calibers like the ammo engine.
