A Look Back: The History and Development
The .308 Winchester’s Genesis
The .308 Winchester’s story began as a military project, a quest to develop a shorter, more efficient round than its predecessor, the .30-06 Springfield. This quest birthed a cartridge known as the T65, which was then adopted by the US military and NATO, becoming the 7.62x51mm NATO. Its civilian counterpart, the .308 Winchester, was introduced in the late 1950s. Immediately, the .308 Winchester found itself a welcome addition to the hunting scene. It’s versatility and inherent accuracy made it a favorite for hunting medium-sized game animals, while the military’s adoption ensured its ongoing production and ready availability of ammunition. The .308 Winchester’s legacy as a versatile and effective cartridge is undeniable. It has proven its worth across generations.
The .338 Federal’s Development
In contrast, the .338 Federal is a more recent development, born from a desire to combine the benefits of a larger diameter bullet with the efficiency of a short-action cartridge. The .338 Federal’s genesis is directly tied to the .308 Winchester. The principle was simple: Take the proven .308 Winchester case and neck it up to accept a .338-inch bullet. This modification resulted in a round with a higher sectional density and the potential for improved performance on larger game. The .338 Federal was specifically designed with hunters in mind, providing increased stopping power and penetration in a package that could be easily chambered in the increasingly popular short-action rifles. The aim was to create a round that could comfortably handle a wider range of hunting scenarios, from whitetail deer to larger animals like elk and bear.
Exploring Ballistics: A Direct Comparison
Bullet Weights and Types
A fundamental aspect of understanding these cartridges is the examination of their ballistic characteristics. Differences in bullet weight, velocity, and trajectory significantly impact their effectiveness at various ranges.
The .308 Winchester is typically loaded with bullets ranging from 110 to 180 grains, with popular choices including 150 and 165-grain options. This range gives the .308 Winchester flexibility in terms of both target practice and hunting. Heavier bullets tend to offer better penetration, ideal for tougher game, while lighter bullets allow for a flatter trajectory, enhancing accuracy at longer ranges.
The .338 Federal, designed around the larger diameter bullet, typically uses bullets weighing between 180 and 225 grains. This naturally leads to heavier bullet weights, resulting in greater energy transfer and a larger wound channel upon impact. The heavier bullet weight also contributes to enhanced penetration, particularly beneficial when pursuing thick-skinned animals. This higher bullet weight translates into increased energy on target, contributing to a devastating effect on larger game.
Velocity and Energy
Velocity is another critical aspect. The .308 Winchester, depending on bullet weight, usually boasts muzzle velocities that reach speeds up to 2,900 feet per second (fps). The lighter bullets will often attain higher velocities. These higher velocities contribute to a flatter trajectory, extending effective range.
The .338 Federal often sees muzzle velocities around 2,600 fps with its heavier bullet weights. While the muzzle velocity of the .338 Federal is often slightly slower than the .308 Winchester, the heavier bullet, combined with its larger diameter, results in a substantial increase in energy on impact. This difference in velocity and weight significantly impacts their ballistic performance.
Trajectory, Sectional Density, and Ballistic Coefficient
Trajectory, the path a bullet takes from the muzzle to its target, is also worth noting. The .308 Winchester, with its typically flatter trajectory, often offers a slight advantage at longer ranges. This flatter trajectory makes it easier to compensate for bullet drop, enhancing the chances of an accurate shot at extended distances.
The .338 Federal’s trajectory is generally more pronounced due to the heavier, slower-moving bullets. At longer distances, the bullet will drop more, requiring more careful holdover adjustments. However, the .338 Federal’s bullet drop remains manageable for many hunting scenarios, and its increased energy transfer often compensates for any slight trajectory disadvantage.
Sectional density (SD) and ballistic coefficient (BC) are often crucial for hunters. Sectional density is a measure of a bullet’s ability to penetrate, while ballistic coefficient describes how effectively a bullet retains velocity in flight. The .338 Federal, with its heavier bullets, generally boasts a higher sectional density. This results in deeper penetration. The .308 Winchester benefits from the smaller caliber and higher velocities offering a more favorable BC to retain speed further.
Performance Analysis: On the Range and in the Field
Target Shooting and Accuracy
The practical applications of these cartridges become most evident when considering their performance in both target shooting and hunting scenarios.
For target shooting, both cartridges offer a good degree of accuracy, however, there are aspects that separate the two. The .308 Winchester often provides an edge in terms of available loads and ammunition, allowing target shooters to find the perfect load for their rifles. Recoil is generally mild, making it comfortable for extended range sessions.
The .338 Federal’s increased recoil can sometimes be a drawback for target shooting, however, the heavy bullet weight makes wind drift less of a factor. The energy transfer in a target often provides a satisfying experience for the shooter.
Hunting Applications: Game Suitability
When it comes to hunting, the .308 Winchester shines as a versatile performer, especially for hunters pursuing medium-sized game. Whitetail deer, antelope, and other similar animals are readily taken with a well-placed shot from a .308 Winchester. The wide range of bullet weights available allows hunters to tailor their load to the specific game they are pursuing and the expected hunting environment.
The .338 Federal is well-suited for tackling larger, tougher game. It excels when hunting elk, black bear, and even moose, offering superior stopping power and deeper penetration. Its ability to transfer substantial energy, even at moderate ranges, makes it a potent choice for hunters seeking to bring down larger animals quickly and humanely. The .338 Federal’s effectiveness is enhanced by its heavy bullet weights, ensuring it carries significant energy downrange.
Recoil and Handling
Recoil is an essential consideration for both. The .308 Winchester offers a manageable recoil, making it comfortable for shooters of all sizes and experience levels. This allows for fast follow-up shots if required, and allows for hours of practice.
The .338 Federal, with its heavier bullets and the higher resulting energy, produces noticeably more recoil. This increased recoil is something that should be considered, particularly if you are recoil-sensitive. A well-fitted rifle and proper shooting technique can help mitigate the impact, but shooters should be aware of the difference before committing to a .338 Federal rifle.
