I shot a new load for me in the 308 A-Bolt today. 22 inch barrel. 47.0 grains of Varget with a standard WW primer. 150 grain Nosler Partition. Shot pretty well and clocked 2729 fps. I have trouble getting much over 2750 with 150 grain bullets in this rifle. I have tried several combinations. So far this rifle has grouped best with plain old Remington Corloks factory loads. Groups about 1 1/4 inches with that load. I have not chronograhped the Remington factory load as yet.
