Hornady's powder is most likely a variant on their Superperformance powders. Some time ago, perhaps during development, someone brought up that it was a St. Marks powder, and Hornady never disputed that, which also fits the Superperformance envelope. 2520 is not as temp stable as the Hornady loads seem to be, so that's a non starter for me.
Interesting that it looks like CFE, because I have seen no copper fouling from the factory loads, and I've noted almost no copper fouling after I shoot it behind my handloads, regardless of what powder I use. That could be my barrel, but it is intriguing.
Does it smell like CFE, which has a very distinctive pepper smell?
Drifter beat me to the temp. sensitivity issue.

You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
