Generally, yes, but it would depend on the trajectory, cavitation, and exit. Any arterial damage would result in a spurting spray, venous would be a more slow oozing. Somewhat rarely, a clean through and through of soft tissue leaves little outside damage and has less bleeding than expected.

Continued heavy bleeding would also largely depend on the subject remaining alive, no? Once Kennedy got hit by that head shot (regardless of which direction one wishes to believe it came from) that was his moment of death, regardless of when they got around to "making time of death official".

Good point. My viewpoint is that JFK died the moment half his brain went flying over Dealey Plaze, not when some doctor pronounced him "dead."

Basically. Some bleeding can occur afterwards but not "heavey bleeding," usually.

As a practical comment - ok, but not really. Essentially, death doesn't occur until the heart has stopped and resuscitation efforts fail (many states include the absence of brain activity for the official definition). Was Kennedy a goner with the head shot, yep, but you don't give up.
