Everybody has their opinion but the NBT has never failed me and has accounted for the most deer sized game i have shot in regards to bullets.I will continue to use it and notch my tag on our large bodied deer. I don't shoot them in the shoulder on broadside, ribs only and never had one not pass through. I have taken a number with the 1/4 high lung out the opposite shoulder this has resulted in a DRT occurance, though the opposite shoulder is pretty messy. 50 or less is the result for yards after the hit and the blood trail is blind man worthy.
