The above example assumes the bullet strikes the deer in it's center of mass, and the resulting motion is purely linear. However, there is a good case to be made for strikes that hit somewhere other than the center of gravity. In this case, the deer will get less linear velocity, and will have some rotational velocity caused by the 'torque' of the impact. The farther the strike is from the center of gravity, the more torque will be generated. It wouldn't be too difficult to calculate the torque generated by a spine hit or a front/rear hit, but the resulting rotational velocity would be very difficult to calculate because you would need to know the deer's moments of inertia.
That is all I am tryong to say. Thank you. I realize it is difficult to prove whether or not it is knocking or nerves but it sure seems like some knocking has taken place a time or two.
