Thanks anthony for the enlightening!!! However having harvested over 20 deer with 130/277 or 150/284 NBT I stand by my comments. I don't aim at the shoulder point with the NBT, I see absolutely no reason to do so and therefore I have never experienced a problem with the BT in the tube. I am glad to see you have picked a bullet that is better suited to your usage and agree with your suggestions for such placement or if you are wanting insurances to let her fly at tough angles. However the BT didn't fail it was just pushed beyond its design limits...hence why I made the original comments.

BTW, I have used the AB to harvest deer, elk and moose(none of which I felt the need to aim for the shoulder, ribs and through both lungs = dead animals in a very short manner). I have also used other bullets so my comments aren't based on blind faith but rather my experiences in the field.

It boils down to picking the right bullet for the task, if that is done the "bullet failure" posts or talk we see/hear are greatly reduced.
