All published 9,3x62 loading data is based on old, low-pressure standards. I have NEVER run into any sort of "pressure sign" by starting with published maximums and working up to around 2450-2500 fps with 286s and 2650-2700 fps with 250s, of whatever brand. That's with three different 9.3x62s hat had 21-24 inch barrels.
No doubt it could be pushed even harder, but have generally found 250s and 286s at those velocities kill big game VERY well.
Thanks MD I've used your load of 65 grains of big game with 286 gr bullet. Get right at 2500 fps with that load with no issues. I'm shooting for the 250's to be in the 2600-2650 fps range and I'll be plenty happy with that.
