While neither powder would be my first choice you might start off at about 70 gr with a max of74.8 with IMR 4831 and a max of74.6 of IMR 4350.

with weatherby brass, 77-80 gr of IMR 4831 with 165 gr bullets, is accurate in every 300 I ever tried it in. Start around 75gr and work up. If it's not weatherby/norma brass start about 4 grains less. The old sierra accuracy load was 80gr.
