48.5 grains of CFE223 works with both the Nosler 120 BT and the Barnes 120TTsx.

Of the newer powders out there, I've had better results with CFE223 than Big Game with the 120NBT and the 7mm-08. One rifle, an 18" carbine, makes over 3,100fps with a charge from the Hogdon online data. Their data is likely warm. Other rifles of mine get H4895 and 120's, using Barnes' load data for their TTSX. That bullet gets close to 3,000fps from a 20" barrel with a max book charge, but I've backed it down to around 2,950. Very pleasant.
