Why, my own grandfather shot a moose with his 38-55 at a measured 2,852 yds, 2' 6" (a surveyor was with the group). Unfortunately for him, it was across a 5-mile long pond, no canoe was available, and by the time he hiked round to the kill through a sudden blizzard, it had been stolen by a band of hungry Passamaquoddy braves.
This, and stories of even longer shots are quite common around 1:30 AM at the VFW, and Odd Fellows Bar.
I have heard the Abrams tankers bore sight their main guns by hitting fence posts at a mile. For real. Or something close to it.
