"On August 22, a Warrant Officer Benjamin, the leader of the armored platoon in the 1st Regiment of Chasseurs d'Afrique, and his support team broke the world record for long-distance shooting after successfully hitting a target 2.29 miles (3695 meters) away"

"Following this success, the team continued to work with a goal of roughly 2.29 miles in mind. At such distances, a number of factors come into play that could influence the shot, such as atmospheric pressure and slight variations in wind speed."

Does not mention caliber? .50 cal maybe? Or I wonder if one of the lighter rounds the snipers are using now? Would .50, good long range cal. but would it be to heavy a bullet?
