I've seen a couple of estimates on what the speed of the bullet hitting Kennedy's back must have been to make such a shallow wound. Using those figures I calculated how far the bullet would have dropped had it been fired from the TSBD at such low speeds and was surprised at the result. The bullet would have dropped over 20 feet! In other words, a sniper would have had to aim 20 feet high in order to hit the president.
Not believing that figure, I did the same calculation for a high-speed bullet, and found it would have dropped around 3 inches. Now that seemed reasonable, and it gave me confidence that my calculation for the low speed bullet was correct. (The reason for the huge difference between a high-speed and low-speed bullet is that the calculation has a square in it. So a bullet that is a that is, say, a fourth the speed will drop sixteen times as far.)
Since then I've been trying to figure out how to explain the back wound. I can't.
Are there any prevailing theories on how the back wound came to be?
After having read several of the posts on this relevant thread:

I'm left with the feeling there are no prevailing theories. Which is odd, if true, given that researchers have had fifty years to think about it.
