A Tale of Two Cartridges: Origins and Purpose
Understanding the Genesis
The .308 Winchester, born in the mid-1950s, quickly gained recognition as a military cartridge, later adopted by the civilian world. It was designed to be a shorter, more efficient replacement for the .30-06 Springfield, offering similar performance in a more compact package. This allowed for shorter, lighter rifles and faster bolt actions. The .308 Winchester has become one of the most popular hunting and target shooting cartridges globally, and with good reason.
The 500 Auto Max Comes Along
In stark contrast, the 500 Auto Max, a more recent arrival, emerges from a different lineage. It’s derived from the powerful .500 S&W Magnum handgun cartridge, creating a rifle cartridge optimized for use in semi-automatic platforms. The goal was to provide a potent, straight-walled cartridge for specific hunting situations, particularly those where regulations or preferences favor a straight-walled design. Its design allows for a substantial bullet diameter and heavyweight projectiles, delivering impressive downrange energy. This is a cartridge built to be a serious performer.
Examining the Bullet Options: A Look at What Flies Downrange
Bullet Selection for the .308 Winchester
Bullet selection is a pivotal aspect of any cartridge’s performance, greatly influencing trajectory, terminal ballistics, and overall effectiveness. The 308 Winchester enjoys a massive selection of bullet weights and designs. You’ll find bullets ranging from light, varmint-style options to heavy, high-sectional-density bullets perfect for larger game. Common bullet weights include 150, 165, and 180 grains, but the range extends far beyond. Bullet designs for the 308 include full metal jacket (FMJ), hollow point (HP), soft point (SP), ballistic tip, and bonded designs, all tailored for various hunting needs and target shooting disciplines. This cartridge offers unparalleled versatility in bullet choices.
Bullet Selection for the 500 Auto Max
The 500 Auto Max, though newer, offers a more specific selection of bullet options due to its straight-walled case. The dominant bullet diameters will be large. Typically, the selection leans toward heavier projectiles, often in the 300 to 400-grain range or even heavier. These bullets are typically designed for maximum energy transfer and deep penetration. Bullet types often include solid copper, expanding hollow points, and specialized designs intended for both hunting and self-defense, especially in areas where straight-walled cartridges are required for hunting.
Understanding Ballistics: Charts and Real-World Performance
Muzzle Velocity and Energy
To truly compare these two cartridges, we must examine their ballistic performance. Comparing muzzle velocities is a starting point. The 308 Winchester, with its smaller bullet diameter and powerful case, often boasts higher muzzle velocities, sometimes exceeding 2,800 feet per second (fps) or more, depending on the bullet weight and powder charge. This contributes to a flatter trajectory at longer ranges. The higher velocities also give the .308 an initial advantage in terms of energy on target.
Trajectory and Wind Drift
The 500 Auto Max, launching heavier bullets, typically has a lower muzzle velocity, usually ranging from 1,500 to 2,000 fps or so, depending on bullet weight. However, what the 500 Auto Max lacks in velocity, it compensates for with sheer bullet mass and diameter. The large, heavy bullets of the 500 Auto Max carry significant energy, especially at closer ranges. Its ballistic arc will generally be more pronounced than that of the 308 Winchester, especially beyond 200 yards.
The Role of Environmental Factors
Trajectory and wind drift are also critical factors. The flatter trajectory of the 308 makes it more forgiving at longer distances, requiring less holdover for accurate shots. Wind drift will also be somewhat less with the 308’s higher ballistic coefficient bullets. The 500 Auto Max, with its heavier bullets, will be more affected by gravity and wind, especially at longer distances, demanding a more careful assessment of environmental factors. Retained energy is also very important. At close to moderate ranges, the 500 Auto Max’s heavier bullets often retain significant energy, leading to impressive stopping power.
Putting Them to the Test: Applications and Intended Use
Hunting with the .308 Winchester
Hunting applications are central to any discussion. The 308 Winchester, with its flatter trajectory and wide range of bullet options, is a versatile hunting cartridge, excelling at taking deer, elk, and black bear. It delivers excellent performance at ranges from 100 to 300 yards, and even further with proper shot placement and range estimation. The wide selection of hunting bullets makes it a strong choice for various hunting situations and game types.
Hunting with the 500 Auto Max
The 500 Auto Max is a specialist in its own right. The straight-walled design and bullet characteristics make it an excellent choice for hunting large, dangerous game, especially at closer ranges. It’s a popular choice for hunting in areas where straight-walled cartridges are mandated, such as some parts of the United States and Canada. The 500 Auto Max also offers significant stopping power at close range, making it a good option for brush hunting.
Target Shooting and Beyond
Target shooting and competition also see these cartridges put to the test. The 308 Winchester has a long history in target shooting, particularly in bolt-action rifles.
