I don't use 165 Accubonds in a 308, normally I will use Sierra, Hornady boat tails, sometimes bulk Win and Rem. If I had to choose a powder for most loadings & bullet weights in 7.62/308 it would be one of the 4895's, good accuracy decent velocities a middle of the road powder. higher velocities with 165's I will use Varget and it's generally good accuracy. I do shoot semi-auto Military service rifle in 7.62 so I need to run middle of the road powders H-or IMR 4895 to not over port pressure the system. bolt guns BLC-2 , IMR 4064, IMR 30-31, 4895's are all decent it just depends on what the rifle likes, but I would run them on a Chronograph , I would stay away from 4831 type slow powders in the 308
