Does anybody have a good source for Superformance data? I finally broke down and ordered some from Powder Valley. I'll have to get the Newest edition of Hornady manual, no biggie. I was just wondering if anyone had a good online source for it.
For a powder that will work in 243 and 30-06 I would expect so see data for stuff in between like 308 or 270.
Superformance has a burn rate Slower than the 4831's. It is way to slow for the 308, so you will never find tested data for the 308.
I count at least 9 different factory loads offered by Hornady in 308 and Superformance powder. Here is just one.

I have a couple of boxes, I can't quite get the 3000 fps, but was close. Accuracy was pretty good. A bit over 1 MOA, and not quite as good as my handloads, but not bad.
Data for reloaders is scarce, but Hornady uses it in a lot of factory loaded cartridges.
So there are different Superformance powders? And only one is currently available for handloaders. Am I understanding this right.
