3000 Yards = 1.70454545 Miles
My burst. Math was never my strong suit.

.45-70 at Two Miles: The Sandy Hook Tests of 1879
RIFLE MAGAZINE, NOVEMBER-DECEMBER 1977
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!
Ya know, it's always that last 5/10,000 of an inch that confuses me:
Do they measure the front of the bullet, or the back of the bullet, when it stops after 3000 yards?
