I went with the majority and voted shot placement but I have to agree with peetzakilla. If you shoot someone with a .50 BMG in the arm or the leg the poor SOB is proably going to bleed out very quickly or be otherwise incapacitated. On that note, does anyone know about the terminal ballistics of the .500 SW? I believe that is a very relavant piece of info regarding this question.
