Rifles are like people they'll tell what they like to eat if you'll listen . I must confess that I too would consider 3031 a bit fast for an '06 . Over the years & with numerous rifles I've had better luck with 4895 to 4064 speed powders & 150gr bullets . With 165's usually 4350 , RL19 , W760/H414 works the best . 180's seem to like 4350 to 4831 speed powders . Of course these are generalizations , but they're backed up by years of my experiences . If your rifle likes 3031 use it . I've got a 358Win that loves 3031 w/ Sierra 225 spitzer .
