Strange firearms accident
According to news reports, a hunter fired a muzzleloader in the air, and killed an Amish girl over a mile away. I don't think a round ball would go that far, let alone arrive with lethal force. Perhaps a modern saboted projectile could do it -- although those are essentially pistol projectiles, and I believe the max (not max lethal) range of a .45 is 1.1 miles. As I recall, increasing the muzzle velocity only slightly extends range, since it's largely offset by higher wind resistance.
