Weapons: Growing Popularity of 8.6mm Sniper Round

Archives

October 9, 2007: The British Army is replacing most of its 3,000 7.62mm L96A1 sniper rifles with one modified to use the .338 (8.6mm) Lapua Magnum caliber round. The Accuracy International "Super Magnum" rifle is basically a L96A1 "Arctic Warfare" rifle modified to handle the larger, 8.6mm Lapua Magnum round. The new rifle (the L118A1) weighs 15 pounds (without a scope), is fifty inches long and has a 27 inch barrel and a five round magazine.

Snipers in Iraq, and especially Afghanistan, have been calling for a longer range round, but find the 12.7mm (.50 caliber) weapons too heavy. The .338 (8.6mm) Lapua Magnum round has an effective range (about 1,500 meters) about 50 percent greater than the 7.62mm standard NATO round. The 8.6mm round entered use in the early 1990s, and became increasingly popular with police and military snipers. Dutch snipers have used this round in Afghanistan with much success, and have a decade of experience with these larger caliber rifles. British snipers in Afghanistan are also using the new round.

Recognizing the popularity of the 8.6mm round, Barrett, the pioneer in 12.7mm sniper rifles, came out with a 15.5 pound version of its rifle, chambered for the 8.6mm.
