The En-Bloc ejection system on a rifle like the Paravaccini Carcano works very differently from the M-1, not being gas operated, the system doesn't operate with nearly as much force, and the En-Bloc doesn't get kicked around.

Felix, it's physically impossible to operate a Paravaccini Carcano rifle at one shot a second, 3 shots in 5.6 seconds, with an En-Bloc clip is a hell of a stretch, but if he loaded the rounds individually (which he must have) we're talking out of the ballpark impossible. Besides, it's nigh-on impossible to operate most semi-automatics at any reasonable accuracy (let alone perfect, 100% head-popping accuracy, as in the case of Port Arthur, which makes the case against Bryant kinda ridiculous) at greater than one shot a second, which the Zapruder film clearly establishes.
