The main thing to consider is COL, mine are seated way out and are 10 thou off the lands, 46 grn of Hodgdon superprofrmance would be a light load in my rifles with the 143 ELDX.
Every rifle is different, when you say pressure what are you seeing.
RL26 is another good powder for the heavy pills that shows low pressure.
