You should stop swigging bleach.
You've doubled down on your ignorance once again:
1) Head shot: Cavitation created the explosive effect. That's the point.

2) Back/Neck-junction inshoot: FMJ ammo is designed to remain intact when passing through human flesh.
What about when it struck the T1 vertebrae?
Now let's see you lot squish your heads to the extent that the butt-end portion of CE399 was, and still call it pristine.
Pristine refers to loss of material, not a slight deformation. No bullet comes out of a barrel "Pristine", as you define it. BTW, did anyone bother to note how much material gets lost as the bullet travels thru the barrel? And where is a single re-enactment of a FMJ bullet striking 3 bones, causing 7 wounds then magically showing up slightly flattened and pristine (99% intact), with no DNA on it? That's the only study that could convince me.
Why do you keep clutching at straws and bending over backward to defend the WC? Oh right, because you sold your soul long ago to the LN hypothesis and you are seeing it thru come hell or high water. Good luck with that. Every coup needs rubes to pull it off. As long as there is not a 100% consensus that Oswald was a patsy, then the WC wins. They won because LNers jumped thru hoops to defend their Report for them. They relied on all CTs to be painted as tinfoil mad hatters and discredited their conspiracy theories by lumping them in with bigfoot sightings and UFO abductions. Today, the LNer approach is to clutch at straws to explain every single contradiction and anomaly re this case, because it's 1 strike and you're out for a LNer. If there is 1 chink in the armor then it is all over, Oswald was not a lone nut and the WC loses.
Maybe Oswald knew he was the designated patsy. Maybe he smuggled the rifle into the TSBD in pieces inside a paper bag. Maybe he took some shots from the SN and wiped off all his prints, ditched the rifle, bought a coke from a vending machine in the lunchroom within 90 secs. Maybe the MC wasn't leaky enough to deposit any nitrates on Oswald's face as he took the shots. Maybe Oswald was such an elite sharpshooter he could pull off a headshot using a crap rifle with a wonky scope and no practice. Maybe the magic bullet did zig-zag thru JFK and Connally and showed up on the wrong stretcher in near-pristine condition. Maybe the DPD were just incompetent and not nefarious when it came to handling the evidence and serving up Oswald to Ruby. But what part of those "maybe"s exclude Oswald from being a pasty? You are not really a LNer, you are a WC Defender, because Oswald was a patsy, not a lone nut.
