## Understanding the .338 Lapua Magnum
The .338 Lapua Magnum (8.6x70mm) is a centerfire cartridge designed for extreme long-range shooting and anti-personnel use. Developed in the 1980s as a joint venture between Lapua and Accuracy International, it quickly gained popularity among military snipers and long-range enthusiasts. It bridges the gap between standard military cartridges like the 7.62x51mm NATO and the much larger .50 BMG.
### Core Concepts and Ballistics of the .338 Lapua
The .338 Lapua Magnum achieves its performance through a combination of bullet weight, velocity, and ballistic coefficient. Typically, it fires a .338-inch diameter bullet weighing between 250 and 300 grains at velocities exceeding 2,700 feet per second. This results in a flat trajectory and significant energy retention at long distances. Recent advancements in bullet design have further enhanced its ballistic performance.
The .338 Lapua’s high ballistic coefficient allows it to resist wind drift and maintain velocity over long distances. This makes it exceptionally accurate in challenging conditions. Furthermore, its energy transfer upon impact is substantial, providing excellent stopping power.
