I remember hearing about an officer involved shooting that happened at around 15 feet inside a parking garage,the officer was using a department issued 12 gauge with 9-pellet '00 buck.
The officer unloaded every round he had in the shotgun,before going to his handgun,the whole time shots were being fired the BG was advancing on the officer,the perp then gave up when the officer drew his handgun.
All pellets hit their mark in the perp's upper body.
After all was said and done the officer admitted that he should have went for a head shot,the perp died on the way to the hospital.
So please oh wise one tell me again how the 12 is so much better than any other gauge.
