W760/H414 have always been the ideal speed and accuracy combo champs for me with 140-150 weights. Had good luck with faster powders nd lighter bullets: H335 and Varget; RL19 and 7828 work well with the heavies; 4350 with 160s. Those are my results. I doubt you'll have trouble putting the rifle to work with what you have though.
Second this - W760 gets 'er done with 140 Accubonds or 145 Hot Cors - both in velocity and accuracy. Varget or RL-15 both work well with 120 gr bullets.
