Walt imo, , it’s not quite enough to prove beyond doubt that the MC rifle that Lt.Dau is lifting up from the floor was NOT fired at 12:30 pm 11/22/63.
However the WC does NOT prove beyond doubt that the rifle WAS fired at 12:30 on 11/22:/63.
So it seems that what remains is the question of why there’ was apparently no commentary offered by the expert)s) about gunpowder residue found in the breech/ camber and in the grooves of the bore that could prove the rifle was fired at 12:30 previous to its discovery by Boone at 1:22pm.
There does not appear to be any statement by the “experts” made about the residual odor of gunpowder that should have been noticeable when the rifle was in proximity to the noses of Will Fritz and Lt Day as they were closely examining the rifle per the Aleya film.
the WC proposes that the shells found in the SN were matched exclusively to the MC rifle Lt. Day is lifting up in the Aleya’s film. IDK if this is true or if it proves those shells were fired at 12:30 11/22/63 or if they were fired a day or week or month earlier and simply left at the SN.
There is still the question if the CE 399 bullet matches with the worn corroded barrel grooves and firing pin of the MC rifle Lt Day lifted off the floor per Aleya film.
