Nonsense.
The fact that the clip can be seen protruding from the rifle does not mean that it had been forced out by hand. It had worked it's way out due the handling of it by Day.
If the Carcano clip is seen protruding from the rifle bottom, it needs to be dislodged/extracted by hand. The opening at the bottom of the rifle is Wider than the Clip. What do you think is holding the Clip inside a space that is wider than it is? It is jammed as Mytton's You Tube visual aide demonstrated.
If the clip Worked its' way out of the rifle "due to the handling of it by Day", then the Clip would have been Rattling around inside the weapon as I stated earlier. You disputed the "rattling" at that time. Now, you are trumpeting this. You are inconsistently grasping at straws due to being unfamiliar with the operation of the rifle.
