Hodgdon updated their load data website recently, (a few weeks ago I think). I was checking 338-06 load data and was surprised to see StaBALL6.5 listed. The velocities for 210, 225 and 250 grain bullets were the highest listed for those bullet weights. I haven't tried that powder yet, but will when it's available. I'd be curious to see how that powder works in 9.3 x 62. Sorry, haven't helped with your request, but I'd keep my eyes open for any load data for your cartridge with this powder.
