Legendary sniper Gunnery Sgt. Carlos N. Hathcock II was the first person to ever use a .50 caliber weapon in a sniping role. Utilizing a .50 caliber Browning HMG with an 8-power telescope sight, he set the record for the farthest confirmed kill by a sniper during the Vietnam War, at 2,250 meters.
This feat of field craft by Sgt. Hathcock established the viability of using .50-caliber ammunition as usable and effective for sniper special operations. Sgt. Hathcock’s record was broken only recently in Afghanistan by a Canadian sniper team. The Canadian snipers scored a chest shot at 2,430 meters using a .50 caliber McMillian bolt-action rifle, with a 16 power Leupold telescope sight.
