We're on the same page here. I'm going from memory and my visit to the Depository - there was one mostly intact bullet found on the stretcher. It was roughly 90% whole, the rest were fragments. Just saying that stuff like that happens.
Not sure what you mean by "blunt or ball" ammo......
Yes, confusing.
I believe the idea was that full metal jacket ammo was supposed to be more humane! Wounding an enemy is preferable to killing them outright because it creates a greater logistical strain on your opponent. That was also an argument in favor of the adoption of the AR/M16 and the 5.56 NATO 'high velocity' round.
That 6.5 Carcano has a blunt, rounded nose. Military cartridges of the era tended toward 'spitzer' style -pointy - bullets to achieve accuracy over greater distances. Still do. At 100 yards Oswald didn't need the increase in efficiency. I was just saying there's a difference between blunt rounded types and the 'spitzer' style pointy ones which have been in use since the late 19th century. The 6.5 Carcano was a thowback. It will still f*** you up if shot in the head or throat from short range, obviously. Quite capable of doing what was done to JFK and Governor Connally.
Military FMJ ammo is universally called 'ball'. Anachronism. Here's some Minie 'balls' and 1969 vintage .30-06 military 'ball' ammo. Neither are really balls but both are referred to as such.
I just post this stuff because it's too common to draw conclusions from reading on the internet, and when it comes to what is and isn't possible in terms of rifle shots it's a narrow window into which I have some insight.
