What is the .338 Lapua Magnum? A Deep Dive

The .338 Lapua Magnum (8.6×70mm or 8.58×70mm) is a rimless, bottlenecked centerfire cartridge designed for military sniper rifles. It sits between cartridges such as the .300 Winchester Magnum and the .50 BMG in terms of size and power. The .338 Lapua offers a flatter trajectory and greater resistance to wind drift compared to smaller calibers, making it ideal for engaging targets at ranges exceeding 1,000 meters. It is known for its exceptional accuracy, high energy retention, and ability to defeat body armor at long distances.

History and Development

The development of the .338 Lapua Magnum began in the early 1980s by the Finnish company Lapua (now Nammo Lapua). The goal was to create a cartridge that would fill the gap between existing sniper cartridges and the much larger .50 BMG. The project was initiated in response to requests from military forces seeking a cartridge with superior long-range performance and armor-piercing capabilities. The .338 Lapua Magnum was designed to be effective against both personnel and light armored vehicles.

Cartridge Specifications

The .338 Lapua Magnum cartridge has a bullet diameter of .338 inches (8.6 mm) and a case length of 2.756 inches (70 mm). The cartridge typically uses a 250 to 300-grain bullet, with muzzle velocities ranging from 2,700 to 3,000 feet per second. The cartridge’s design allows for high ballistic coefficients, which contributes to its excellent long-range performance. The large case capacity allows for a substantial powder charge, resulting in high muzzle energy.

Ballistic Performance

The ballistic performance of the .338 Lapua Magnum is exceptional. The high ballistic coefficient of the bullets used in this cartridge allows it to maintain its velocity and energy over long distances. This results in a flatter trajectory, reduced wind drift, and increased impact energy at the target. The .338 Lapua Magnum is capable of delivering lethal hits at ranges exceeding 1,500 meters, making it a favorite among long-range shooters and military snipers.

The McMillan TAC-338: A Premier Rifle for the .338 Lapua
