Volley Fire at 300 yards, and what Civil War bullets sound like in flight

After a few attempts... we master the art of firing crisp volleys at the 300 yard range. Civil War bullets, like the Burton Minie ball we were shooting, slice through the air with a bone chilling sound that cannot be described, but our high-tech downrange camera systems (old iPhones...) actually did a great job recording the sound. Pretty epic.
