Norman says …… Boom-click-click……. Boom-click-click…… Boom-click-click.
Norman says …… Boom-click-click……. Boom-click-click…… Boom.
Norman contradicts hizself – he said he heard 2 empty shells – he said he heard 3 empty shells.
I don’t know whether Norman's above click-click is (1) the bolt being pushed back and then forward, or whether the click-click is (2) the bolt being pushed back & forward & then the sound of the empty shell hitting the floor.
Anyhow, i had a look at a Carcano on youtube.
The bolt is forward & down. The Carcano is empty – no bullet – no clip.
Loading a clip (5 bullets).
click (bolt lift) – clack (bolt back) -- now ready to load clip down into Carcano.
clip-clip-clip-clip -- there were a few soft clips & 1 loud clip in the middle when loading the clip.
Loading the first bullet. The bolt is initially up & back.
clock (bolt forward) – clock (bolt down) – now ready to shoot.
Shooting & reloading.
Bang (the shot) …… click (bolt lift) – clack (bolt back)(eject) – clockk (bolt forward)(& then bolt down)(combined) – klunk (hull hitting ground).
Clockk – this was a combined bolt forward & bolt down – making one combined sound.
Klunk – this was more of a thud here when hitting ground, or it was a klink if hitting another shell on the ground -- or of course it would be a klunk if hitting a wooden floor (or a klunketyklunketyklunk).
The clockk & the klunk were at the same time, or the klunk was sometimes slightly after (difficult to tell).
So, what sounds could Oswald have made?
[ a ] In a simple case he is ready to pull the trigger, & fires 2 shots, in which case Norman might hear….
Bang …… click-clack-clockk-klunketyklunketyklunk.………. (Oswald then takes aim).
Bang …… click-clack-clockk- klunketyklunketyklunk.
Oswald then duznt pull the trigger to fire his last bullet.
[ b ] If for some reason Oswald was not ready to pull the trigger then Norman might have heard….
click-clack-clockk-klunketyklunketyklunk (very old empty shell ejected)(& bullet loaded) ……… (Oswald then takes aim).
Bang …… click-clack-clockk- klunketyklunketyklunk ………. (Oswald then takes aim).
Bang …… click-clack-clockk- klunketyklunketyklunk.
Oswald then duznt pull the trigger to fire his last bullet.
In [ a ] Norman hears 2 shells hit the floor. In [ b ] Norman hears 3 shells hit the floor.
In both [ a ]&[ b ] Norman would have heard the Baaannggg of Hickey's auto burst say 6 seconds after Oswald's 2 Bangs.
