I dont think there is enough mass in a bullet or shot to physically move someone like in the movies is what their summation was.
it’s not “mass” you’re worried about; it’s mass times velocity squared. Can add up to a lot of foot-pounds.
Law enforcement buddies, as well as military buddies, have confirmed to me that people who are shot with bullets are blown backwards, sometimes significantly so.
The myth was the body flying backwards not falling down.
