I was trying to find some load data for hodgon Superformance powder in my 243 and can’t seem to find any published data for it. I usually load RL15 but ended up with a little Superformance and wanted to give it a try. I wanted to load 95gr SST’s and or 62gr or 68gr Berger. Thanks!

I use Superformance in my 243's. I get great groups with 58 gr. to 85 gr. bullets using 44 gr's of Superformance. I drop to 43 Grs. with bullets heavier. I get more speed with less pressure and the same goes for loads in my 22-250.
 
Here's a page from the Hornady's 10th
Handbook. The 95 grain SST is listed and matches the data @milboltnut listed from #9. No Berger bullets are listed in Hornady's manual of course. Looks like you'll need Hodgdon's data linked above by @0.1 Aggregate for the others.

Have you ever choreographed the 58s with this combo?
