I believe you will find that powders such as W760, H380, H414, IMR4350 and RL19 will give you the best combination of velocity and accuracy. Somewhat faster powders that should give good performance but slightly less velocity would include Varget, IMR4064 and RL15.
My personal choice would be whichever of these (W760, H380, H414,RL19) gave me the best combination of accuracy and velocity. All are equally suitable but barrels being what they are your rifle will likely favor one over the others. Which only your rifle can tell you.
