how did you come up with this pic and get it posted so fast?
About six months ago a new guy decided to give some of us a lecture on bullet trajectory at long range and said a bullet was falling fast enough to that it could hit the back bone and then pass through the heart. So I had the picture on the server from then.
There are actually two bones - the shoulder and the blade. The shoulder is a large and tough bone and the blade is of varying thicknesses just like on a deer. On a deer or elk you only have about a 30-40% chance of getting a bullet into the chest without hitting a bone of some kind.
My interest stems from the fact that I used the predeccessor to the AMax on an elk and it would not break the bone at an equivalent impact velocity. That is the same bullet that Yobuck likes to shoot. So the question on the table is the Amax tougher than I believe or was the bone not struck and broken. It is important to know what doesn't work as well as what does work i. e. what is the point of failure.
It is just a question to try to actually learn something, which is one of the chief reasons for being here.
