A Brief History

The .338 Winchester Magnum was introduced in 1958 by Winchester. It was designed as a versatile cartridge suitable for a wide range of big game, from elk and moose to bears. It quickly gained popularity for its relatively flat trajectory and substantial stopping power at moderate ranges.

The .338 Lapua Magnum, on the other hand, is a much newer cartridge, developed in the 1980s and gaining prominence in the 1990s. It was designed specifically for military sniping applications, offering superior long-range performance and armor-piercing capabilities compared to existing cartridges. The 338 Lapua quickly became a favorite among special forces and law enforcement snipers worldwide.

Ballistics and Performance

The most significant differences between the 338 Win Mag and 338 Lapua lie in their ballistic performance. The 338 Lapua, with its larger case capacity, can handle heavier bullets at higher velocities, resulting in a flatter trajectory and greater energy retention at extended ranges.

Velocity and Energy

Typically, a .338 Winchester Magnum firing a 225-grain bullet will achieve a muzzle velocity of around 2,800 feet per second (fps), generating approximately 3,900 foot-pounds of energy. In contrast, a .338 Lapua Magnum firing a 300-grain bullet can reach muzzle velocities of 2,700-2,800 fps, producing over 4,800 foot-pounds of energy. This translates to significantly more downrange energy for the 338 Lapua.

Trajectory

The higher velocity and ballistic coefficient of the 338 Lapua‘s bullets result in a flatter trajectory, reducing the need for extreme elevation adjustments at long ranges. This makes it easier to engage targets accurately, especially in windy conditions. The 338 Win Mag, while still capable at long ranges, will exhibit a more pronounced bullet drop, requiring more precise range estimation and ballistic calculations.

Effective Range

The effective range of the 338 Win Mag is generally considered to be around 800-1,000 yards for ethical hunting or accurate target shooting. The 338 Lapua, however, extends that range considerably, allowing for accurate engagements beyond 1,500 yards, and in some cases, even exceeding 2,000 yards in the hands of skilled shooters. This extended range is a key factor in the 338 Lapua‘s popularity among military snipers.

Recoil

Recoil is a significant factor to consider, especially for extended shooting sessions. The 338 Lapua generates substantially more recoil than the 338 Win Mag due to its larger case capacity and heavier bullets. This increased recoil can be challenging for some shooters, potentially affecting accuracy and causing fatigue.

The .338 Winchester Magnum produces a manageable recoil level, similar to other magnum cartridges like the .300 Winchester Magnum. Most experienced shooters can handle it comfortably. The 338 Lapua, however, can be quite punishing, requiring a well-designed muzzle brake and proper shooting technique to mitigate the recoil effectively. Shooters new to magnum calibers may find the 338 Lapua intimidating.

Rifle Availability and Cost

Rifle availability and cost are important considerations when choosing between these two cartridges. The 338 Win Mag has been around for much longer, and as such, rifles chambered in this caliber are more readily available and generally more affordable. You can find a wide range of bolt-action rifles from various manufacturers chambered in 338 Win Mag.

Rifles chambered in 338 Lapua, on the other hand, tend to be more expensive and specialized. These rifles are often designed for long-range precision shooting and feature heavier barrels, more robust actions, and advanced stock designs. While the availability has increased in recent years, they still command a higher price point than 338 Win Mag rifles. [See also: Best Long Range Rifles Under $2000]

Ammunition Cost and Availability

Ammunition cost is another critical factor. 338 Lapua ammunition is significantly more expensive than 338 Win Mag ammunition. This is due to the more complex manufacturing process, the higher-quality components used, and the lower production volumes. Expect to pay considerably more per round for 338 Lapua.

While 338 Win Mag ammunition is more affordable, it’s still not inexpensive compared to more common calibers like .308 Winchester or .30-06 Springfield. However, the price difference between the two cartridges is substantial, making the 338 Win Mag a more economical choice for practice and high-volume shooting.

Availability can also be a concern, particularly during periods of high demand. While both cartridges are generally available from major ammunition manufacturers, 338 Lapua ammunition may be harder to find in local gun stores, especially in rural areas. Online retailers are often the best source for finding a wide selection of 338 Lapua ammunition.

Hunting Applications

Both the 338 Win Mag and the 338 Lapua are capable hunting cartridges, but they are best suited for different types of game and hunting scenarios. The 338 Win Mag is an excellent choice for elk, moose, bear, and other large game animals at moderate ranges. Its manageable recoil and readily available ammunition make it a practical choice for most big game hunters.

The 338 Lapua, with its superior long-range performance, is better suited for hunting in open terrain where long shots are common. It’s also a good choice for extremely large or dangerous game, such as African buffalo or polar bear, where maximum stopping power is essential. However, its high recoil and ammunition cost make it less practical for general-purpose hunting.

When selecting a hunting cartridge, consider the typical ranges you’ll be shooting at, the size and toughness of the game you’re pursuing, and your tolerance for recoil. The 338 Win Mag is a versatile choice for most big game hunting applications, while the 338 Lapua excels in specialized scenarios where long-range performance and maximum power are required.

Target Shooting and Long-Range Competition
