Hodgdon CFE 223 is an excellent powder for the 223 remington, right on par with BLC-2, which is a kissing cousin, that is so close, the loads are almost identical for every bullet weight, with CFE 223, maybe a half grain faster on maximum charges.
When it was first offered, some folks even commented it was BLC-2, only enhanced with copper fouling eliminators.
They may be right. Maybe Ganderite could chime in on this???
