1. The core issue: What is the CT explanation for the conspirators planting a suspiciously non-deformed bullet, fired from Oswald's rifle, at Parkland on a stretcher of unknown provenance? Did they prepare CE 399 in advance - WHY? Was this the best they could do? Why would this goofy scenario even have OCCURRED to sane conspirators? Why would they even NEED this bullet? Was this part of the game - "Just for the hell of it, let's make this more fun by doing something SO goofy it raises a hundred red flags " - ?. It makes UTTERLY no sense. All the red flags cut exactly in the opposite direction - i.e., in favor of authenticity and against conspiracy. You have to assign conspiratorial motives because you're stuck with this evidence, but the supposed conspiratorial motives MAKE NO SENSE. If you can, provide your rational explanation for what sense a planted CE 399 makes.
2. As ballistics-types have pointed out, CE 399 is in fact seriously deformed. It is anything but pristine. The fragments in Connally mesh well with the weight of the lead lost.
3. It was Connally himself who described a sound no louder than a wedding band hitting the floor. This just happens to match pretty perfectly with the cuff link that a nurse in fact found and gave to Nellie.
4. If a bullet or large fragment fell out of Connally's thigh and went pinging on the floor, one might think Connally's doctors would have noticed or been alerted. Dr. Charles Gregory, however, was mystified that there was no such bullet or fragment: "We were disconcerted by not finding a missile at all. Here was our patient with three discernible wounds, and no missile within him of sufficient magnitude to account for them, and we suggested that someone ought to search his belongings and other areas where he had been to see if it could be identified or found, rather."
5. Ken Rahn in 2001 published an extensive analysis of the fragments actually found:

https://kenrahn.com/JFK/Scientific_topics/NAA/What_follows.htmlSure, the Magic Bullet is problematical, there was understandable chaos at Parkland, and there is conflict and confusion in the testimony. This is why starting point is to ask the questions posed in #1 above. Instead CTers want to make every issue into Evidence of Conspiracy, simply bypassing the somewhat larger issue of Whether and How This Makes Any Sense.
