Cartridge Origins and Development
The .338 Winchester Magnum’s History
The .338 Winchester Magnum, born in 1958, is a product of Winchester’s ambition to create a high-performance cartridge specifically for hunting large game. It arose from the need for a cartridge with increased stopping power and improved long-range performance compared to existing cartridges. Winchester essentially necked down the .375 H&H Magnum case to accommodate a .338-inch bullet. This gave hunters a powerful and relatively flat-shooting option ideal for elk, moose, bears, and similar species. It quickly gained popularity, earning a reputation for delivering impressive energy on target at reasonable distances.
The .338 Lapua Magnum’s History
The .338 Lapua Magnum emerged in 1989, from the Finnish ammunition manufacturer Lapua, who was looking to fill a specific niche: long-range precision shooting, and by extension, military and law enforcement applications. The goal was to produce a cartridge capable of exceptional accuracy at ranges previously thought unattainable. The .338 Lapua Magnum was designed to push a heavy bullet at a high velocity, providing exceptional external ballistics and a significant edge in terms of effective range. The cartridge was developed in collaboration with Sako and brought the modern, specialized design of the long-range shooter’s dream into reality.
Contrasting Design Philosophies
The contrasting design philosophies are quite clear. The .338 Winchester Magnum was conceived for hunting, balancing power, range, and recoil in a relatively manageable package. The .338 Lapua Magnum was designed with military precision, target accuracy, and extended ranges at the forefront, potentially sacrificing factors like recoil in the pursuit of ultimate performance.
Ballistic Performance: Comparing the Numbers
Bullet Weight and Selection
Bullet selection is a critical factor that affects trajectory, wind drift, and terminal performance. The .338 Winchester Magnum typically handles bullet weights ranging from 180 to 300 grains, with popular choices falling in the 200-250 grain range. This allows for versatility when choosing bullets depending on the size of the game and the desired range of engagement.
The .338 Lapua Magnum, designed for heavier bullets, generally employs projectiles in the 250-300+ grain range. This added bullet weight contributes significantly to downrange energy retention and a higher ballistic coefficient which results in greater effectiveness at very long ranges. The increased weight also adds to recoil, which is a factor when choosing your rifle.
Muzzle Velocity
Muzzle velocity is where the .338 Lapua Magnum clearly asserts its dominance. Depending on the specific bullet weight and powder charge, the .338 Win Mag will generate velocities in the neighborhood of 2600 to 3000 feet per second (fps). In contrast, the .338 Lapua Magnum, benefits from a larger case volume allowing for muzzle velocities of up to 3200 fps. The Lapua’s higher velocity translates to a flatter trajectory and less wind drift, key elements for effective long-range shooting.
Trajectory and Range
The difference in trajectory is particularly noticeable at extended distances. While the .338 Win Mag offers a relatively flat trajectory compared to many other hunting cartridges, the .338 Lapua Magnum maintains a flatter trajectory even at extreme ranges. For example, at 500 yards, the .338 Win Mag might experience a drop of approximately 20-25 inches, while the .338 Lapua Magnum might see a drop of 15-20 inches, all depending on the bullet used. At 1000 yards, the disparities widen. The .338 Win Mag could see a drop exceeding 100 inches, while the .338 Lapua Magnum could manage a drop of around 70-80 inches. It is all dependent on the bullet type and weight, of course. These differences allow the Lapua to have the edge at extreme distances.
Energy at Impact
The energy delivered at impact is a direct consequence of both bullet weight and velocity. The .338 Win Mag can deliver substantial energy at moderate ranges, sufficient for large game hunting. But the .338 Lapua Magnum’s combination of heavier bullets and higher velocity results in superior energy retention at longer distances. This means that the .338 Lapua Magnum maintains more energy on impact at 1000 yards and beyond than the .338 Winchester Magnum does at a much shorter distance. This enhanced downrange energy is crucial for reliably achieving ethical kills on big game or for effectively engaging distant targets.
Ballistic Coefficients (BC)
The ballistic coefficient (BC) measures how efficiently a bullet overcomes air resistance. A higher BC means less drag and a flatter trajectory. The .338 Lapua Magnum typically utilizes bullets with a much higher BC than the .338 Winchester Magnum. For instance, a premium 300-grain .338 Lapua Magnum bullet might have a BC in the .800 range, compared to .650 for a 200-grain .338 Win Mag. This is crucial for long-range precision because a higher ballistic coefficient translates to less wind drift, less bullet drop, and greater retained velocity and energy over long distances.
Rifles and the Associated Equipment
Rifle Availability and Price
The choice between .338 Win Mag and .338 Lapua Magnum also involves considering the rifles themselves, the accessories needed, and the associated costs.
Rifles chambered in .338 Winchester Magnum are relatively common. They are produced by several major manufacturers and can often be found at a more affordable price point compared to .338 Lapua Magnum rifles. The typical action size for the .338 Win Mag is a long action.
Rifles chambered in the .338 Lapua Magnum, however, require larger and heavier actions due to the size of the cartridge. They are generally more expensive, reflecting their more specialized nature and greater precision. The .338 Lapua Magnum often sits in a magnum action, which is specially designed to handle the greater pressures and length of these cartridges.
Action Size and Weight
The weight of the rifle plays a significant role in managing recoil. Rifles chambered in .338 Win Mag, generally lighter and more compact than those in the .338 Lapua Magnum. This can be advantageous for carrying the rifle through rugged terrain. The .338 Lapua Magnum rifles, on the other hand, tend to be heavier, absorbing some of the recoil. This contributes to mitigating felt recoil, although the overall impulse will still be higher.
Optics and Accessories
Suitable optics and accessories are vital for both cartridges. For .338 Win Mag rifles, scopes with moderate magnification (e.g., 3-15x or 4-16x) often suffice for the typical hunting ranges. The longer ranges that can be exploited by the .338 Lapua Magnum necessitate more powerful scopes (e.g., 5-25x or higher). High-quality glass, accurate reticles (e.g., MOA or MIL), and external adjustment turrets are highly recommended for both cartridges. Other accessories, like a good bipod or monopod, are indispensable for achieving precision at long distances. Muzzle brakes can also be added to both cartridges, but they will significantly amplify the sound and may require hearing protection at all times.
Practical Considerations: Recoil, Cost, and Availability
Recoil
Recoil is an important consideration. The .338 Win Mag, while powerful, is generally considered manageable for most shooters. A good rifle design, proper technique, and the use of a recoil pad will often mitigate some recoil.
The .338 Lapua Magnum, generating substantially more recoil, demands a solid stance, proper technique, and a willingness to learn to manage the recoil. Experienced shooters often use muzzle brakes or compensators to reduce felt recoil, although these options can increase the muzzle blast.
Cost of Ammunition and Components
Ammunition and reloading components cost varies for both of these rounds. Commercial .338 Win Mag ammunition is readily available from a variety of manufacturers, with a wide range of bullet styles and weights. The .338 Lapua Magnum ammunition is generally more expensive than the .338 Win Mag.
Reloading and Availability
If you are a handloader, both cartridges can be reloaded. The .338 Win Mag has greater availability of reloading components. The .338 Lapua Magnum has a more limited selection, but it is still possible to tailor loads for precise needs. Reloading is especially important for long-range precision shooting, as it allows the shooter to develop the most accurate and effective loads for their particular rifle.
