I'll let you find your own charge weight - 4064 has been incredibly consistent powder for me in the 30.06. For long range having consistency out the end of the barrel is something to behold. Yes velocity will minimize wind drift, but having a low ES and SD contribute to the same drop amount at the long ranges involved in distance shooting.
Lots of options though. Hogdon powders have less temperature variance for me than most powders, I'd avoid the double base powders when looking for temperature stability.
