Decoding the .338 Caliber: Federal vs. Lapua
The .338 caliber has become a popular choice for hunters and long-range shooters seeking a balance of power and manageable recoil. Both the .338 Federal and the .338 Lapua Magnum fall under this umbrella, but their design philosophies and performance profiles are vastly different. Understanding these differences is key to appreciating their respective strengths and weaknesses.
.338 Federal: The Mid-Range Marvel
The .338 Federal is a relatively newer cartridge, developed by Saffle & Sons, and later adopted by Federal Premium Ammunition. Its design centers around providing .338 caliber performance in a short-action rifle platform. This is achieved by necking up the .308 Winchester case to accept a .338 diameter bullet. The result is a cartridge that delivers impressive energy and trajectory out to medium ranges (typically considered 400-500 yards) without the need for a magnum action or excessive recoil.
The beauty of the .338 Federal lies in its versatility. It’s suitable for a wide range of game animals, from deer and antelope to elk and even black bear. Its manageable recoil makes it a comfortable option for shooters of varying experience levels, and its compatibility with readily available .308 Winchester actions keeps rifle costs relatively reasonable.
.338 Lapua Magnum: The Long-Range Legend
The .338 Lapua Magnum, on the other hand, is a purpose-built long-range cartridge. Developed in the 1980s by Finnish company Lapua, it was designed to provide superior performance at extreme distances, particularly for military and law enforcement applications. The .338 Lapua Magnum utilizes a larger, more robust case than the .308 Winchester, allowing it to handle significantly higher pressures and propel heavier bullets at higher velocities.
This translates to flatter trajectories, greater energy retention, and superior wind resistance at extended ranges. The .338 Lapua Magnum is capable of accurately engaging targets well beyond 1000 yards, making it a favorite among long-range shooting enthusiasts and professionals. However, this performance comes at a price. The .338 Lapua Magnum generates substantial recoil, requires a magnum action rifle, and ammunition is considerably more expensive than .338 Federal.
Ballistic Performance: A Head-to-Head Comparison
The ballistic performance of a cartridge is a critical factor in determining its suitability for a particular application. Several key metrics influence ballistic performance, including velocity, energy, trajectory, and wind drift. Let’s examine how the .338 Federal and .338 Lapua Magnum stack up in these areas.
Velocity and Energy
Velocity is the speed at which the bullet travels, while energy is a measure of its kinetic energy. Generally, higher velocity and energy translate to flatter trajectories and greater stopping power. The .338 Lapua Magnum boasts significantly higher velocity and energy figures than the .338 Federal, owing to its larger case capacity and higher operating pressures.
For example, a typical 250-grain bullet fired from a .338 Lapua Magnum can achieve a muzzle velocity of around 3000 feet per second (fps) and a muzzle energy of over 5000 foot-pounds (ft-lbs). In contrast, a similar weight bullet fired from a .338 Federal might achieve a muzzle velocity of around 2600 fps and a muzzle energy of around 3700 ft-lbs. This difference in velocity and energy becomes even more pronounced at longer ranges.
Trajectory
Trajectory refers to the path of the bullet in flight. A flatter trajectory is desirable because it reduces the amount of holdover required to compensate for bullet drop at longer ranges. The .338 Lapua Magnum’s higher velocity results in a significantly flatter trajectory than the .338 Federal, especially beyond 300 yards. This makes it easier to accurately engage targets at extended distances.
Wind Drift
Wind drift is the amount the bullet is deflected by the wind during flight. The .338 Lapua Magnum’s higher ballistic coefficient (a measure of its ability to resist air resistance) and higher velocity make it less susceptible to wind drift than the .338 Federal. This is a crucial advantage in windy conditions, where accurate shot placement can be challenging.
In summary, the .338 Lapua Magnum offers superior ballistic performance compared to the .338 Federal, particularly at longer ranges. However, this performance comes at the cost of increased recoil and ammunition expense.
Recoil Comparison: Comfort and Controllability
Recoil is the force exerted back on the shooter when a firearm is discharged. Excessive recoil can be uncomfortable, reduce accuracy, and even lead to flinching. The .338 Federal and .338 Lapua Magnum differ significantly in their recoil characteristics.
The .338 Federal, designed for use in short-action rifles, produces a manageable level of recoil that is comparable to a .30-06 Springfield. Most shooters find it comfortable to shoot for extended periods without experiencing excessive fatigue. This makes it a good choice for hunters who may need to take multiple shots or for shooters who are sensitive to recoil.
The .338 Lapua Magnum, on the other hand, generates substantial recoil. The recoil energy can be more than double that of the .338 Federal, making it a challenging cartridge to shoot accurately, especially for inexperienced shooters. A well-designed muzzle brake and a heavier rifle can help mitigate the recoil, but it remains a significant factor to consider.
Ultimately, the acceptable level of recoil is subjective and depends on the individual shooter’s tolerance and experience. However, it’s important to be realistic about the potential impact of recoil on accuracy and shooting comfort. For most shooters, the .338 Federal offers a more manageable and enjoyable shooting experience.
Rifle Availability and Cost
The availability and cost of rifles chambered in .338 Federal and .338 Lapua Magnum can vary significantly. This is an important consideration when choosing a cartridge, as it can impact the overall cost of ownership.
Rifles chambered in .338 Federal are generally more affordable and readily available than those chambered in .338 Lapua Magnum. This is because the .338 Federal is compatible with standard short-action rifle platforms, which are widely produced by many manufacturers. You can find .338 Federal rifles from companies like Savage, Kimber, and Sako, often at prices comparable to other popular hunting cartridges.
.338 Lapua Magnum rifles, on the other hand, require a magnum action to handle the cartridge’s higher pressures and larger dimensions. This necessitates a more robust and expensive rifle design. .338 Lapua Magnum rifles are typically offered by specialized manufacturers such as Accuracy International, Barrett, and SAKO, and they often come with a premium price tag.
Ammunition Cost and Availability
The cost and availability of ammunition are also important factors to consider when choosing a cartridge. .338 Lapua Magnum ammunition is significantly more expensive than .338 Federal ammunition. This is due to the cartridge’s larger size, more complex manufacturing process, and lower production volumes.
A box of 20 .338 Lapua Magnum cartridges can easily cost twice as much, or even more, than a box of 20 .338 Federal cartridges. This price difference can quickly add up, especially for shooters who practice frequently or engage in competitive shooting. Availability can also be a factor, with .338 Lapua Magnum ammunition sometimes being more difficult to find in stock at local gun stores.
