Second question: Would a .25 caliber bullet fired from a 6.5 MM Carcano 91/38 "bounce around" inside the barrel, possibly acquiring the anomalous land/groove markings that we see on CE 399? I'm imagining that the bullet hits first "side A" on the barrel, then "side B", then back to "side A", only because the bullet isn't tightly gripped by the lands/grooves, the second time it hits "side A" it isn't quite in the same rotational state, so it acquires a second set of land/groove markings on that side...
BTW CE 141 (the unfired bullet from inside the rifle) does appear to be .264 not .268 (or .257) in diameter, based on the ruler in the picture.
No, I don't think a .25 calibre bullet was fired at JFK, at least not from an M91/38 anyways.
It is hard to say what would happen to a .25 calibre bullet fired from a 6.5mm Carcano rifle, especially if the barrel of that Carcano was worn extensively. As there would be next to no contact with the lands, the bullet may not spin at all, and may just exit straight out the end of the barrel; albeit at a much reduced velocity due to the propellant gases escaping past it.
Mr. HILL. The right rear portion of his head was missing. It was lying in the rear seat of the car. His brain was exposed. There was blood and bits of brain all over the entire rear portion of the car. Mrs. Kennedy was completely covered with blood. There was so much blood you could not tell if there had been any other wound or not, except for the one large gaping wound in the right rear portion of the head.
