1. Animals fall down reliably if a vital organ is destroyed, regardless of sectional density of the bullet.
2. Animals fall down reliably if the bullet retains enough weight and has enough speed to penetrate to a vital organ regardless of sectional density. This is interesting, weight and speed are the factors that determine momentum and energy values.
3. The sectional density value seems to be of no importance at all, providing it did not disappear completely.
4. The post impact sectional density of a bullet is almost always less than the starting sectional density.
This leaves only one question unanswered. Who first came up with the theory of sectional density? Was it some ballistician with a macabre sense of humour? Did he put forward this theory as a joke and it got out of control? Sectional density seems to be the ballistic equivalent of an internet chain letter. No matter how illogical or outdated or disproved it is, it keeps on popping up. Almost like the concept of hydrostatic shock, but that is another story.
