The 308 Winchester, born from the military 7.62x51mm NATO cartridge, first saw civilian life in the mid-1950s. It quickly gained popularity for its impressive balance of performance and manageable recoil. This round is well-known for its versatility and ability to be chambered in a wide variety of rifle platforms. Its popularity stems not only from its performance but also from its abundance of ammunition, readily available throughout the world. The standard bullet diameter for the 308 Winchester is around 0.308 inches. This cartridge has seen extensive use in hunting, offering sufficient power for medium to large game animals, and its reasonable recoil allows for greater accuracy with consistent shot placement. Within target shooting, the 308 Winchester has a strong presence, used in competition shooting where the accuracy and manageable cost are appreciated. Further, the 308 has been a standard cartridge for military and law enforcement snipers for decades. Its performance on the battlefield and in controlled environments has established the 308 Winchester as a time-tested and well-respected round.
338 Lapua Magnum
The 338 Lapua Magnum, a more recent arrival on the scene, emerged in the late 1980s. Designed specifically for extreme long-range performance, it quickly earned a reputation for reaching distances that other rounds simply couldn’t achieve. The 338 Lapua Magnum has a considerably larger case and employs a bullet diameter of approximately 0.338 inches. This design results in superior ballistic performance and long-range capabilities. The 338 Lapua Magnum is built for long-range target shooting. Target shooters benefit from the cartridge’s ability to withstand wind deflection, offering consistency at extended ranges. It is also a prime choice for military and law enforcement snipers who demand extreme accuracy and stopping power at extended distances. The 338 Lapua is known for its ability to deliver more kinetic energy to targets compared to the 308 Winchester.
Ballistic Comparison
The performance of any round is best understood by examining its ballistic characteristics.
Muzzle Velocity and Energy
Muzzle velocity and energy are crucial indicators of ballistic performance. The 308 Winchester, in typical loadings, can achieve muzzle velocities ranging from roughly 2,500 to 2,800 feet per second (fps), depending on the bullet weight and propellant. The 338 Lapua Magnum, given its larger case capacity and greater propellant volume, produces substantially higher muzzle velocities. Expect muzzle velocities typically exceeding 3,000 fps, with some loads pushing beyond this benchmark. The resulting muzzle energy is significantly greater as well. The 338 Lapua Magnum can easily deliver more than double the muzzle energy of the 308 Winchester. The difference in these values directly influences several aspects of long-range performance. Higher muzzle velocity means a flatter trajectory and reduced time of flight, both contributing to improved accuracy at extended distances. Higher energy translates to greater impact, making the 338 Lapua Magnum a more potent choice for those seeking maximum downrange impact.
Ballistic Coefficient and Trajectory
Ballistic coefficient (BC) measures a bullet’s ability to overcome air resistance. A higher BC indicates that a bullet will retain its velocity and energy over distance. The 308 Winchester typically uses bullets with BCs ranging from moderate to good, depending on bullet design and weight. The 338 Lapua Magnum is often loaded with bullets of very high BC values, contributing to its superior performance in windy conditions and at long ranges. These differences in ballistic coefficients translate to differences in trajectory. The flatter trajectory of the 338 Lapua Magnum becomes increasingly evident at extreme ranges. The 308 Winchester, while accurate in its range, begins to drop noticeably more at greater distances.
Effective Range
Effective range, or the distance at which a round can consistently deliver acceptable accuracy and terminal performance, is a crucial factor. For the 308 Winchester, this range typically extends to around 800 to 1000 yards, though skilled shooters can often push these limits. The 338 Lapua Magnum, however, consistently delivers effective performance far beyond that. It has the capability to hit targets accurately at distances of 1500 yards or even beyond. These longer effective ranges make the 338 Lapua Magnum the premier choice for applications where distances are significant and where reaching the target consistently is crucial. Factors like wind, atmospheric conditions, and the shooter’s skill will, of course, always affect the maximum achievable effective range.
Performance in Different Applications
The effectiveness of these rounds varies according to the application.
Long-Range Target Shooting
For long-range target shooting, the 308 Winchester remains a popular choice, especially for those looking for a good balance of cost and performance. It is frequently employed in various target shooting disciplines where ammunition availability and cost are considerations. The 338 Lapua Magnum, though more expensive, is the preferred option where the goal is to maximize distance and minimize the impact of wind drift. Its exceptional ballistics offer a decisive advantage. It provides unmatched performance and a higher likelihood of hitting targets at extreme distances, despite the increased cost and recoil.
Hunting
In the realm of hunting, the 308 Winchester excels for game animals of moderate size. Its accuracy and manageable recoil make it a good all-around choice for hunting where the distances are not excessive. The 338 Lapua Magnum, however, offers significantly greater energy delivery, making it appropriate for larger game at greater distances. The 338 Lapua is especially useful where a high degree of penetration and stopping power is required, but it may present challenges in terms of increased recoil and its more limited availability. Hunter selection will always depend on what game is to be hunted, the distances anticipated, and the legal regulations that may be in place for any given area.
