Anyone using Superperformance in the Creedmoor?

Boy-howdy!
Have burned over 16# of it in the Creedmoor, and have Pressure Trace data for it. Very stable across temps, and is very progressive in burning. What I found is that you can back off pressure by 10,000+ psi, and will only lose @50 fps because of the changing burning curve.
My first few lots were FAR slower than Hornady data (12%), the newest jug is spot on.
As to where to get it, it's all over the place.
Grafs, Midsouth, Bruno Shooters, etc.
