I've killed elk with 7mm NBT and TTSX 150 grains out of a 7 RM over 300 yards with excellent results from the TTSX and good and bad from the Nosler. What convinced me though was breaking bones with exits on a big boar at over 500 yards with the Barnes, that isn't something that the Nosler would be good at. Accubonds didn't shoot well or perform well on deer, that is where the NBT is the best choice in my experience .
