However there is no reason that a we'll trained person shooting from the hip can't be effectively accurate at HD ranges.
Sure there is....because no WELL
-trained person is going to use that methodology.......
Hip shooting is great in Hollywood movies, as is the spray and pray methodology used in video games
Unfortunately, life is neither a Hollywood movie or a video game - there is no "do-over" switch when something goes wrong
Anyone with any modicum of balance and coordination can reflexively point better than aim and do it faster - do it home with your off-trigger hand's index finger and eyes closed to point to a spot on a wall like a light switch - then close your eyes and get you red-dot tacky-cooled shotgun and try to do the same as fast. That time you spend trying to focus your eye through the scope will usually mean you're dead in a real time scenario
