Bob: Are you thinking that the shooter fired .25 caliber ammo thru his gun to kill JFK, or that the FBI has substituted .25 caliber bullets as stand-ins for their ballistics work?
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.
