More feasible with a shot that enters from behind at the Z220s rather than through the shoulder from the side at Z271.
Show us. I gave you the baby with shoulders turned and looking backward. Not a great model but it was the only thing I could find. A shot through the armpit on a downward path (JBC was also leaning back) comes out around the nipple on the same side. Where is your photo?
He could see you were showing him manipulated drawings with shoe-horns, so he entertained you and gave you a noncommittal answer to get rid of you.
I believe Dr. Gregory had a drawing showing the bullet might have gone through the wrist on the outer side of the radius. It is of a left hand because he was drawing with his right hand. It has been flipped below.

I don't know, but the Xray seems to show the "criss-cross" that could be an impact point is on the outer side of the radius.
Don't you still have to have a fragment exit the palm side at Z271?
The impact is definitely on the back/top or dorsal side of the wrist. It struck the radius hard enough to break off at least 2 shards that were removed from the wound and it dragged wool fibres into the wound. But the exit wound on the palm or volar side of the wrist could have been made by a bullet fragment or a secondary missile such as a bone fragment. This was contemplated by Dr. Shaw (6H91):
Dr. SHAW. Ordinarily, we usually find the wound of entrance is smaller than the
wound of exit. In the Governor’s wound on the wrist, however, if the wound
on the dorsum of the wrist is the wound of entrance, and this large missile passed
directly through his radius, I’m not clear as to why there was not a larger wound
of exit than there was.
Mr. SPECTER. You mean out through the wrist than it did?
Dr. SHAW. Yes; if a whole bullet hit here--
Mr. SPECTER. Indicating the dorsal aspect?
Dr. SHAW. Yes; and came out through here, and the bone was left in the wrist-the bone
did not come out. In other words, when it struck the fifth rib it made a hole
this big around (indicating) in the chest in carrying bone fragments out through
the chest wall.
Mr. SPECTER. Wouldn’t that same question arise if it went through the volar
aspect and exited through the dorsal aspect?
Dr. SHAW. It wouldn’t if you postulated that the bullet did not pass through
the wrist, but struck the wrist.
Mr. SPECTER. That would be present in either event, though, if you postulated
if the bullet struck the dorsal aspect of the wrist, and did not pass through, but
only a missile passed through the volar aspect.
Dr. SHAW. Yes;...
Now, Mason, isn't there the bulk of a Stetson hat between Connally's right hand and his chest? Yet you have his right hand against his chest.
That's what it looks like, Jerry. The stetson is below the wrist. He is holding the brim.
