I have used H335 and BLC2 in my 9.3X57 which is a lesser capacity case due to much smaller shoulder. The 9.5x57 is like an AckleyIMP case, in comparison.
If you want my data as a starting point let me know.
BTW, I was running over 2,500fps with all of those bullets at safe pressure in the model 96 Husky. ZERO pressure signs with ZERO case expansion at the web 3/8" above the extractor groove over a sized case. My mic measures to the ten/thousandths.
