Have you ever noticed the greatly relied on device used in the movies where a character will emotionally discharge a big gun of some type? I guess the reaction is supposed to characterize a last gasp burst of attack against a nearly undefeatable opponent (Independence Day: Resurgence). Terminator Salvation has multiple examples of actors unloading weapons’ magazine after magazine in an attempt to stop a non human juggernaut. To get an idea of what I am referring to, please go to the clip. You can probably get away with this type of behavior at the target range.
