I had the opportunity to do some more testing with the 140gr mrx and the results are that one of my 7mmstw rifles is averaging 5/8" groups,but the other is not nearly as good at around 1",and not nearly as consistent.Velocities were 3450fps for one rifle and 3475fps for the other.At this point,I have decided that I will use this bullet in one rifle but not in the other,as it just hasn't shown the consistency that I demand.Now it's just a matter of fine tuning the load for the one rifle.
