Did any of the goats shot in those experiments undergo explosive head exit wounds or explosive exit wounds of any kind? If not, what is the relevance to the physics of the explosive head wound?
A goat's brain-case would not be comparable to a human's.
I heard it was called watermelon helper
Was the military in on some conspiracy to use sub standard gels?
The science of ballistics in 1964 wasn't that advanced such that they had a specific simulant for human brain.
I thought you were the one arguing against being too demanding on exacting standards of reproductions of the head shot? I am now confused about your standards
The melon experiments demonstrate the principal of "jet effect", which is what is seen in Z313
ff. If you're after a duplication of the Kennedy head wound dynamics, you'll need an elaborate model with a bone-like casing and ballistic gel that simulates the human brain.
However the bullet could enter the center of the back of the skull and exit through the frontal bone. You would get "jet effect" but complain about it the trajectory being off-target. You would have to redo the experiment until all the things necessary converge. Say on the 100th try everything works right. But now you can say there was only a one-percent chance that the head shot was caused by a SN bullet that then produced "jet effect".
But the bullet that struck Kennedy in the back of the head was as unique in where it struck as that one-percent of duplication shots.
