The canister version of Superformance is not the same powder they are using in their factory ammo. Superformance canister powder is just a slow burning powder with a nice, gentle pressure curve (very similar to Winchester 780 Supreme). The bulk powder they load in factory ammunition is BLENDED. You'll probably never see it for sale to the general public.

One of the reasons for the lack of data, is that Hornady and Hodgdon don't publish data for that powder, unless it shows an increase in performance over existing data. If it's just another powder in the list... they don't publish. If it shows a 75+ fps increase over the previous "best" load, you'll see it in the Hodgdon reloading center. And... the 2011 Hodgdon reloading guide has a warning, not to use bullet/cartridge combinations not published for Superformance. Whether there are legitimate safety risks, or they don't want bad publicity, due to sub-par performance... I don't know.

To me, it's just another powder. It only looks super-mega-awesome, because they are picking and choosing which "amazing" loads they publish data for; while quietly holding back the loads where it can't beat the existing data.
