I had a 7mm ballistic tip 150 grain more or less blow up on a bull's ribs from 250 yards quartering away. The entry wound was the size of your palm and he covered over 500 yards before the shrapnel in his lungs bled him out. It was an easy trail to follow in the snow but a long way have a wounded elk walk that was hit right where I aimed.
Since then I've gone with Barnes TTSX bullets and will stick to deer sized game with the NBT's. They work great most of the time but id rather not take the chance that they wont at the wrong time.
