When I had a .30-06 I used either 150's or 165's and I sort of preferred the 150's. I used whatever suitable powder I had left over from other rifles. I had many good times shooting Hornady .308 150 SST's with H414/W760, RL15, Varget, RS Big Game& RS Hunter. Velocities were all around 3,000 fps and on occasion I shot up to 600 yards with good results. I would like to try StaBall with 150's in the .30-06. Excessive recoil & heat for volume rodent shooting. Some time before, when shooting NRA Hi Power during the transition between .30-06 & .308 many .30-06 shooters used either 150 or 168 grain bullets with IMR4064 and this powder became some sort of a standard for the .30-06. WWII was partially won with 150 gr. (or real close) .30-06 loads.
