13. 2 Men in protective gear have a match in the Olympic Event of Pistol Dueling at the 1906 Olympics in Athens, Greece. They used wax bullets, and competed with speed and accuracy being the key, similar to old west shootouts that most of us have seen heavily exaggerated in films. No gun powder, just the primer, which was enough to propel the wax bullet. This Olympic event, as one might guess, did not take off.
