Has any research been done on the terminal effects of  keyholing 5.56 rounds vs  5.56 rounds flying properly at close quarters distances??  I'm just curious if a keyholing round could be more devastating to flesh at ranges where the accuracy doesn't matter as much?  Your thoughts???

You might read up on the performance of the very early M-16's w/ 1:14" twist bbls in Vietnam.

Key holing will only help if you have chosen a fragmenting otm and its hitting with enough velocity to still fragment.   This is not needed.  If you are worried or want faster break up, change your bullet.  77gr SMKs penetrate the deepest before fragmenting.  Then Hornady 75gr.  The Nosler 77gr has the shorest neck of all the heavy 75-77gr otms.   The nosler has a neck of about 1inch.

Why? Those rounds weren't tumbling in flight and keyholing.  They destabilized when they hit flesh (just like they do out of a 1/12 or 1/9 or 1/7 twist).
