Whatever gives good accuracy in that range. I would prefer to do 800-X as a final option even though I will hand weigh all charges since these are very important loads for large angry animals.
That bullet profile looks very similar to the Double Tap and Beartooth 200 gr. WFNGC hardcast bullets. Beartooth has a double groove like the one you show above. My experience below is not with your particular bullet, but the bullets I mention above. Stock G20 4.6" barrel.
Of the powders that you mention, I did workups with 800-X and Accurate no. 9. Accurate no. 9 gave about 50 fps better velocity (1205 fps average), tighter groups and velocity spreads, and brass looked less "tired" than those from the 800-X loads at 1150. For 800-X, I was a good ways over book maxes, and with Accurate no. 9, I was still within at least one book load.
Back when Speer still made a 200 gr. TMJ, they and Accurate posted load data for that bullet for Accurate no. 9. Accurate's max was 13.5, and Speer's was 14.0. Splitting the difference between the two gave solid results. I did not have any worrisome indications of excessive pressure, but did not see any reason to go higher. A 200 gr WFNGC hardcast bullet @ 1205 fps is a smacker.
BT and DT have a bhn of 21, and I did not notice what the hardness of the Going Ballistics bullet is, so please workup carefully.
