Yes Paul I have played with the seating depth, and tried a dozen different powders, 8 different bullets in a hundred + combinations. Never got any better then 1.25" groups (165gr SGK HP/Big Game with Remington Brass) My 150gr and 180 bullets went sub-MOA first time out, I have just come to accept that my 308 does not like 165-168gr for whatever reason and I am OK with that if I want 165s shooting .5 MOA I will break out my 30-06 which shoots them just fine with IMR/H4350.
