You can learn a lot from watching bullet hits in slow motion.
But, you really need to do the same shot hundreds of times to understand the general principal in a statistically valid way.
We need to do some testing to understand the JFK thing.
Unfortunately we need to test many different calibers, each caliber with many different loads, and each caliber/load combination from a variety of distances and angles.
A lot of ammo will be needed and perhaps millions and millions of 'targets'.
Fortunately, there is an adequate supply of targets and we know where to find them.
Let the science begin.
Ammo....up!
