I would like to open a can of worms and spark some controversy.
To me it looks like there are problems with CE 399.
For example, compare the earliest photos taken of the bullet before the Warren Commission and compare them to later photos at the National Archives.
They don't look like the same bullet.
Here someone has compared the photo on top of the bullet as taken by the FBI shortly after the shooting to a photo of a standard WCC Mannlicher-Carcano bullet.
Notice how thin the jacket appears to be in the upper photo as compared to the bullet in the lower photo.

I would like to see one of the kooks expand on this difference by claiming that CE 399 was not really from Oswald's ammo as the bullet jacket is much thinner than the normal WC ammo.
Now compare the FBI photo to a much later photo taken by the National Archives.

Notice the difference in appearance of the black spot in the middle of the base on both bullets. Slightly different size and shape.
Now for some controversy. My theory is that the black spot seen in the top photo is where the FBI gouged out a piece of lead with a tool to test its chemical composition.
So the ONLY lead missing from the assumed normal weight of the bullet is what the FBI took out for testing. No place to have any tiny fragments deposited in Connally.
Now look at the very first picture taken of the bullet while it was still only known as FBI exhibit C1. The quality is not as good because it is only a Xerox copy of a photograph print stapled to Frazier's evidence sheet.
But it again looks slightly different from later photos taken of the bullet.
The National Archives has never produced the original photograph from which this was cropped.

I am not interested in the kooky theories about the damage to the body of the bullet or discrepancies about the lands and grooves. Just stick to the appearance of the BASE of the bullet.
BTW, the WCC ammo was made to the same specs as the SMI bullet and someone photographed the bases of the two brands next to each other to show how similarly thick the jackets were.
