Bowling with a Shotgun

You know how in the movies people who get shot are picked up and blown backwards 20 feet? This is a 12 gauge shotgun firing slugs, which are far more powerful than Dirty Harry's .44 Magnum, or an AK-47, for that matter. Take note of how it simply knocks the bowling pins down, rather than creating a cloud of sawdust 200 yards downrange.
