So Jim Garrison said, and some people believe him.
BUT: after the Italian Army as a whole reequipped with the .30 M1 in 1952, the Italian Army Marksmanship Team continued to use the Mannlicher-Carcano for more than a decade.
I’ve heard the same story about the M-C...slug the bore to get the true diameter, and “tune” your ammo to suit it (even if it just means sorting and checking diameters of bullets on issue ammo with a mike) and the Mannlicher-Carcano can do very well.
Am I saying that that’s what Oswald did? No...only that even a “POS” rifle can be a tack driver if the stars all align right. And Oswald wasn’t using wartime Italian ammunition...he was using American commercial ammo.
Regarding the backspray of blood when Kennedy was shot...hasn’t it been reported that he was wearing a backbrace that day, which limited his movement?
Biggest issue I have with the idea of Kennedy’s assassination being some sort of “conspiracy”...if this was organized by a group with any sense of planning, why would Oswald have been “allowed” or “enabled” to be captured? Why not have the assassin disappear, leaving no evidence behind...or if a name and face were to be supplied, why not have the “assassin” conveniently killed before capture? For that matter, if it was the work of a conspiracy, why have either the President or assassin taken out in public view?
To leave a triggerman behind, alive and spewing inconvenient claims, reeks of either incredibly bad planning or “failure to think things through”. And that latter element—the lack of planning beyond the “I’M GONNA BE SOMEBODY!” moment—makes me think the events in Dealey Plaza were the work of one loser, a self-declared Marxist True Believer, who had attached himself to the Cuban cause after being disillusioned by the Soviet Union, and sought to make a name for himself by lashing out on its behalf.
