THe ballistics tables are on the web.

This shot was called at 3300 yards in an Amercian version of this story.

Long range shooting isn’t new
(from http://www.researchpress.co.uk/longrange/sandyhook.htm)

- Tests of the 45-70 at SAndy Hook - 1879.

THE SHOOTER at the heavy bench rest squinted as he aligned his .45-70 Allin-Springfield Model 1873 Army rifle on the distant target. The rifle fore-stock and barrel was cradled in a rest; the butt was supported by his shoulder. The rear sight was flipped up to its full height, so with no stock support for his head, the rifle tester from Springfield Armory worked carefully to align high rear and low muzzle sight on the speck that was the target - a surveyed 2,500 yards distant.

Holding his breath, he squeezed the 7-pound trigger. The rifle fired, and some 15 seconds later, signals from the target indicated that his shot had struck well inside the 6-foot diameter bullseye on a target well over a mile away!

At these ranges, it is almost mini-artty.

The rifle fired, and some 15 seconds later

This part seems, odd.

7 pound trigger?

Good grief.

Gravity is only one dimension here. At a mile and a half the wind can be blowing from any direction, maybe several at once, including up and down. They don't have the benefit of a line of flags running downrange to figure that out. Then you have mirage, the varying density of the air can really mess up your perception of the actual location of the target. The greater the range, the greater the effects of all evironmental factors. Pure absolute skill is this rifleman's advantage.
