Mystery Road (2013)

Factual error: Pete Bailey states he uses a Remington 700 rifle to shoot "roos" (kangaroos). The climactic shootout begins when Jay Swan spots Bailey's truck far across the valley. We see a small puff of smoke just before a shot rings out. Two seconds later Swan is struck by the bullet fired by Bailey. Throughout the gunfight the sound of a shot is heard before the bullet arrives. This also happens during the long-range gunfight between Johnno and Bailey. Bullets fired by a high-power rifle (like the Remington 700) are supersonic so the bullet would arrive before you could hear the shot. (01:47:20)
