Contrary to my post from April, I decided to join LoadData a month or so ago. The bullet manufacturers mentioned are all still on the site.
I pulled up .223 for example, and Nosler, Speer, Berger, Sierra, Hornady, and Barnes are all well represented.
It's still a good resource, have no fear. They have loads with the newer powders, such as CFE-223 from Hodgdon, on the site. Every time I log on, they tell me how many new loads were added since my last log on.
Today when I logged on after a week or so, there were almost 700 new loads.
