80-100yds, 3 shots in 8 seconds? This is do able with virtually any repeater, and please remember that "marksman" is the LOWEST qualification.
While I have a great deal of respect for Marine Corps training, a Marine Corps "marksman" award is not given to really good shots. Those people score "sharpshooter" and the best score "Expert". Marskman means you didn't fail qualification, and very little else.
While the Carcano and the scope on it are far from the easiest to use within the allotted time, it has been recreated many times, so arguing about whether or not it could be done is moot.
As to whether Oswald did it/could have done it, well, the Warren Commission and history say Oswald did it. If you don't believe it was Oswald or only Oswald, nothing I can say is going to change your mind. And now, half a century later, I don't much care to argue.
