We checked; a .22-caliber projectile can travel approximately one mile in a straight line.

Uh, no! A .22 can reach one mile if fired at a 45 degree upward angle, resulting in a high arc trajectory.

Once it is fired, it begins to fall to the ground at 32 feet per second. A six foot person firing the rifle level means the bullet would hit the ground in 1/5 second.

The velocity of .22 rimfire rounds is from 1000-1300 feet per second. So in that 1/5 second, the farthest the bullet could go when fired level would be from 200-260 feet.

Therefore, rifles are not fired level. Sights are adjusted so that the barrel is angled upward to the degree necessary to extend its range as needed by the shooter.

Sights do not allow sufficient elevation to reach a mile. Someone had to aim the rifle upwards at a 45 angle, which means it could not have crossed adjoining properties level. It would have been dropping from its high arc.

I think my numbers are close.
Which would also explain how it traveled "through" (actually over) a church and other structures before hitting the poor guy who got shot.
