If you ever decide to push the really heavy bullets in the 9.3x62mm you may consider RL-17, I use it to push the 320 gr Woodleigh protected point Weldcores to a very accurate 2400 fps, that's from my Heym 98 Mauser custom with a 25" barrel.
The load is a real hammer, I'd use it on Cape Buffalo without hesitation were it legal in an area that I hunted.
