The record was set using the largest shoulder-fired firearm in existence: the McMillan TAC-50.
Ryan Cleckner, a former U.S. Army Ranger sniper who served two tours of duty in Afghanistan and wrote the “Long Range Shooting Handbook” was amazed by the shot, especially the skill exhibited by the spotter.
“The spotter would have had to successfully calculate five factors: distance, wind, atmospheric conditions and the speed of the earth’s rotation at their latitude,” Cleckner told Fox News.
“Because wind speed and direction would vary over the two miles the bullet traveled, the true challenge here was being able to calculate the actual wind speed and direction all the way to the target.”
“To get the atmospheric conditions just right, the spotter would have had to understand the temperature, humidity and barometric pressure of the air the round had to travel through.”
