I have used the 150 NBT for a while in my 22 inch long throat 284 barrel. A stiff charge of 2209 pushed them at 2970 fps.
They preformed well from 20 yds to 750.
Ive also used 162 Amax with H414 in a 17 inch barrel (2700 fps) and imr 7828ssc with 162 Amaxs in the 22 inch barrel and can achieve 2900 fps with that.
Im currently running 180 gr eldms in the 22 inch barrel with Re26 at around 2850 fps.
