It's an interesting powder for sure. I've heard from multiple sources that where it shines is in upper-end charges and pressures, aka: it likes pressure.
The listed max for 6creed/110g A-Tips is 42.70g-3047fps(Hodgdon data) and 42.0g -3000fps(Hornady data) for a 24" tube. Mine is 26" and well broken-in/"seasoned" but far from worn out.
I tried a load workup with it yesterday in 6creed with 110g A-Tips, CCI400SRP, new Lapua brass, seating depth was my normal 0.060" off the lands. I disregarded the lower-end starting charges based on the info previously mentioned. I loaded 5 rounds for each .10g from 42.00-42.90 to test. Using a Magnetospeed V3. It was cold, 37F when I started and warmed up to 43F by the time I finished. Humidity 50%, wind was full value 15-18mph right-left (North to South) I think the cold temp kept velocities down. Data obtained below (yes, ES/SD wasn't great, but accuracy was VERY good for several nodes in there. I do trickle to exactly .01g.

42.90: 2948*2,2975*3,2879,2943*4,2946*5 (right at 1/4moa)
*1= semi-heavy bolt lift
*2,*3,*4,*5= only *very* light primer cratering(no heavy bolt lift)
Edit: It is a very dirty powder if using lighter weight bullets or small-rifle primers. I think it really needs a large-rifle or magnum primer to get a cleaner burn and better consistency. It's a pretty slow burning powder.
