A bullet wound to the shoulder isn’t just a flesh wound. Taking a bullet to the shoulder isn’t something you can “work through”. Something like that will have you rolling around in agony unable to focus, or you go into shock. Also bullets don’t always pass through, they can ricochet off bone and travel around the body. A bullet can enter your leg, run up the inside of the body and shread every organ it comes into contact with. They have previously found bullets in the brain that entered via the foot too.
