Accuracy Considerations

Accuracy is paramount in any shooting application, and the choice between 308 180grain vs 308 168grain can influence your results. While both bullet weights are capable of excellent accuracy, several factors can affect their performance in a particular rifle.

Rifle Twist Rate: The twist rate of your rifle barrel is a crucial factor in stabilizing the bullet in flight. Faster twist rates (e.g., 1:10) are generally better suited for heavier bullets like the 180-grain, while slower twist rates (e.g., 1:12) may perform better with lighter bullets like the 168-grain.
Bullet Quality: The consistency and quality of the bullet itself play a significant role in accuracy. Premium bullets with tight tolerances and uniform construction will generally deliver better results.
Shooter Skill: Ultimately, the shooter’s skill and technique are the most critical factors in achieving accuracy. Proper breathing, trigger control, and follow-through are essential for consistent shot placement.
Rifle Quality: The quality of the rifle and its components, such as the barrel, trigger, and stock, will also affect accuracy. A well-built and properly maintained rifle will generally be more accurate.

Finding the optimal bullet weight for your specific rifle often requires experimentation. Try different loads and bullet types to determine which combination delivers the best accuracy.

Recoil Management

Recoil is an important consideration, especially for shooters who are sensitive to it or who plan to engage in extended shooting sessions. The 168-grain bullet generally produces less recoil compared to the 180-grain, making it a more comfortable option for many shooters. This reduced recoil can translate to improved accuracy and faster follow-up shots.

Several factors can influence perceived recoil, including rifle weight, stock design, and the use of recoil-reducing devices such as muzzle brakes or recoil pads. Shooters who are particularly sensitive to recoil may benefit from using a heavier rifle or incorporating recoil-reducing accessories.

Hunting Applications: Choosing the Right Bullet Weight

For hunting, the choice between 308 180grain vs 308 168grain depends largely on the size and type of game you intend to hunt. The 180-grain bullet is generally preferred for larger game animals like elk, moose, and bear, where deep penetration and maximum energy transfer are essential for a quick and ethical kill. Its higher ballistic coefficient also makes it a good choice for longer-range hunting in windy conditions.

The 168-grain bullet can be a suitable option for medium-sized game like deer and antelope, particularly at shorter to moderate ranges. Its flatter trajectory and reduced recoil can make it easier to achieve accurate shot placement, especially for less experienced hunters. However, it’s important to choose a bullet designed for hunting, with reliable expansion characteristics, to ensure adequate terminal performance.

Understanding .308 Winchester Ammunition Types

The .308 Winchester cartridge is available in a wide variety of ammunition types, each designed for specific purposes. Understanding these different types is crucial for selecting the right ammunition for your needs.

Full Metal Jacket (FMJ): FMJ bullets are typically used for target shooting and training. They are relatively inexpensive and offer good accuracy, but they are not designed for hunting.
Soft Point (SP): SP bullets are designed for hunting. They feature an exposed lead tip that expands upon impact, creating a larger wound channel and delivering more energy to the target.
Ballistic Tip (BT): BT bullets are similar to SP bullets, but they feature a polymer tip that improves aerodynamics and enhances expansion. They are a popular choice for hunting medium-sized game.
Hollow Point (HP): HP bullets are designed for rapid expansion and are often used for self-defense or varmint hunting. They are not typically used for hunting larger game.
Match Grade: Match grade ammunition is manufactured to extremely tight tolerances and is designed for maximum accuracy. It is typically used in competitive shooting applications.

When selecting ammunition, consider the intended use and choose a bullet type that is appropriate for the task.

The Role of Rifle Twist Rate

The twist rate of your rifle barrel is a critical factor in stabilizing the bullet in flight and achieving optimal accuracy. The twist rate refers to the distance it takes for the rifling inside the barrel to complete one full revolution. A faster twist rate (e.g., 1:10) means that the bullet will spin faster, which is generally better for stabilizing heavier bullets. A slower twist rate (e.g., 1:12) is typically better suited for lighter bullets.

For .308 Winchester rifles, a twist rate of 1:12 is a common choice and is generally suitable for bullets in the 150-170 grain range. However, if you plan to primarily shoot heavier bullets like the 180-grain, a faster twist rate of 1:10 may be a better option.

Consult your rifle manufacturer’s specifications to determine the twist rate of your barrel. If you are unsure, a gunsmith can measure it for you.
