I have to agree with Tackb and believe that it can be done and good shot for Roadking. I remember my dad taking a whitetail doe at 1232yards (7 tenths of a mile marked off with odometer of truck) on a straight ranch road for a customer one day in either 89 or 90. He was shooting a 264 win mag in Remington 700 BDL using a Red Field 3X9 widefield scope using a 140 grain remington corelokt bullet. The doe was hit behind the shoulder and dropped in the ranch road it was standing. These shots taken back then with lower power scopes were more difficult than the ones taken today with the high power glass.
As for long range shots with open sights look at what some of the buffalo hunters did with their single shots and one document shot made at the 2nd battle of Adobe Walls made by Billy Dixon at 1538 yards with open sights.
Just my 2 cents.

the british service sniper rifle had only a three power scope up till the 60's i think and then they moved to a 6x42?
