The odds of this happening must be massive.
You’ve got the 360 degree horizon to match up to the point you’re having to hit something on the order of 0.00002% of a single degree.
As for elevation, the same type of dynamic comes into play.
Then you’ve got a non-rifling bore with the ball moving like a knuckle ball, varying winds on the trajectory, humidity, earth rotation, you’re wife’s current cycle... well okay that last one is iffy, but this was an unbelievable series of things that had to be just right for this guy to have hit that girl from 1.5 miles away with that sort of gun.
As always a bullet has got to go somewhere and there is Murphy’s law.
