After a lot of experimenting I found that my particular A7 in 300WSM does not like 150gr. bullets at all. The first try with a 165 grain bullet yielded a .75" group. Seating .05 off of lands with W760. I am hoping H4350 will work as well. This rifle easily achieves max. book velocity using 1.5-2.0 grains less powder than Max. book load. Anybody else noticed a preference for the same rifle?
