Yes, I believe strongly in the Speer 168gr Gold Dot for the 308/30-06. I use IMR-4064 pretty exclusively. I have W-748 and would use it if supplies required it.
43.5gr IMR-4064 for the 308, 48.5gr IMR-4064 for the 30-06. I essentially use the loads in military/match type loadings, but terminal performance is first rate, hunting-wise.
Since I'm not fully familiar with your barrels I would suggest starting lower and working up. I use my fired primers are my primary pressure indicators.
I have used these loads in an M1A, M1 Garand, and now, a 20" PA-10. They are accurate and effective. The M1A is gone now, but these loads have been standards for my GI rifles since the mid-1990's.
