These "Experts" couldn't fire three shots in less than 19 seconds? Were they shooting with their toes? I've seen muzzle-loaders fired three times in less than 19 seconds.
Assume that the first shot is locked and loaded. The clock starts with the first shot. That's 9.5 seconds per shot to fire a bolt-action rifle with a multi-shot magazine. A chimp could do it. But maybe not an Italian "firearms expert." I think Oswald bought his rifle from a want ad -- "Italian army rifle,used, never fired, dropped once."
I know some bolt actions are faster than others, but I've never heard of one that takes ten seconds per shot. That's ridiculous.
Well much is made that it cost “$12” or whatever. Not a “quality” weapon by any means. I hate to say it, but Mrs. Kennedy probably said it best “A Shitty Little Communist”.
I've got a bolt action 20 gauge shotgun that's faster than that.
