A lot of the damage of a bullet is this concussive damage, not the piercing damage. Hollywood has been lying to you (apparently real gun experts hate the movie “shoulder shot” because there’s a lot of things to damage there, especially once you take the concussive force into consideration).
For those who are on the fence, don’t watch it. I just did and I regret it. Suffice it to say that the blood loss alone will be critical condition at the very best.
