It's been noted in a few military history books how it didn't perform very well in combat compared to the rifles of other nations. The Italian goverment wanted to replace it for inadequate performance, but it stayed in use because it was cheap. But anyway, this is not definitive either way, but it was a bolt action rifle.
It would be extremely difficult to even be able to fire off 3 shots in the allotted time, and the 1st shot would be the one that was aimed, the 2nd and 3rd would just be load and shoot. But if it had coming from the book depository, the 1st bullet missed ridiculously high and wide, and the third shot was dead on, fired on a moving target through foiliage.
This is the bullet that supposedly caused all those wounds. It would be much more deformed if it had caused all those wounds the official story claims it does.
