You didn't post your final load. I use 56 gr of IMR 4350 behind a 180 GMK w/ Rem 9 1/2 LRM primer and the pressure is high but safe. I have used 59gr behind a 150gr GMK w/ Fed #210 primer and it shot pretty good too but 4064 was better with the 150gr. IMR 4350 in 30/06 loads only shoots well when I keep the pressure near or at max in my gun. Maybe this is what you should explore.
