Hodgen has their new .223 specific powder out now too, supposed to be even cleaner burning and 'cooler'/easier on the barrels. but the military stuff burns just fine as far as I care.
As far as I understand milspec 5.56 ammo is loaded with bulk grade W748. It was developed for longer barrel life in the M16s and increased performance.
And that CFE223 your are referring to. Awesome stuff. it prevents copper fouling. Burn speed is close to W748.
