I think if the tip was hollow, the radiographic density within that triangle would be a lot less dense than what it appears to be on the image (although we are now getting into a small area of a radiograph which should ideally be viewed in its original DICOM format).
I don't know if I have any spitzer projectiles with a hollow tip in my small collection, but if I find one I will X-ray it in various ways and post the images here, if that is of interest.
