It was apparent that the POI on that mile shot was changing as the barrel heated up. The sight picture they showed between some of the first shots and some of the last were completely different. It's not surprising that the experienced long range shooter came in second. He shot last. The person who came in first, also shot first.
It looked like the POI wandered about 4-5 feet to the right as the barrel heated up.
That was my thinking....
Was the barrel fouled for the first shooter? How much time was the barrel allowed to cool between shooters?
What distance was the gun sighted for? To make a 1 mile shot you have to be pretty familiar with a gun and the cartridge it is shooting....did these guys get to study the ballistics of the .338 Lapua before the competition?
