Side-by-Side Comparison: 308 180grain vs 308 168grain

To provide a clearer understanding of the differences between these two bullet weights, let’s compare them side-by-side across several key factors:

The Role of Twist Rate

The twist rate of your .308 rifle’s barrel plays a crucial role in stabilizing different bullet weights. Twist rate refers to the distance it takes for the rifling inside the barrel to complete one full rotation. A faster twist rate (e.g., 1:10) is generally better for stabilizing heavier bullets, while a slower twist rate (e.g., 1:12) may be sufficient for lighter bullets. Most .308 rifles have a twist rate of 1:10 or 1:12, which works well for a wide range of bullet weights. However, if you plan to primarily shoot very heavy bullets (200 grains or more), a faster twist rate may be necessary.

How to Determine Your Rifle’s Twist Rate

You can usually find your rifle’s twist rate stamped on the barrel. If not, you can measure it yourself using a cleaning rod, a tight-fitting patch, and a ruler. Insert the cleaning rod into the barrel and mark a starting point on the rod. As you push the rod through the barrel, observe how far it travels before completing one full rotation. The distance traveled is your rifle’s twist rate.

Recoil Considerations

Recoil is a significant factor to consider, especially for new shooters or those sensitive to recoil. Heavier bullets generally produce more recoil than lighter bullets. The 308 180-grain bullet will generate more recoil than the 308 168-grain bullet. If you’re concerned about recoil, the 168-grain bullet may be a better choice. Recoil pads, muzzle brakes, and proper shooting technique can help mitigate the effects of recoil.

Terminal Ballistics: What Happens on Impact?

Terminal ballistics refers to the behavior of a bullet upon impact with a target. The goal is to achieve sufficient penetration and energy transfer to cause rapid incapacitation. The 308 180-grain bullet is known for its excellent penetration, making it a good choice for hunting large, thick-skinned animals. The 308 168-grain bullet may not penetrate as deeply but can still be effective on medium-sized game with proper shot placement.

Bullet Construction and Design

The construction and design of a bullet also play a significant role in its terminal performance. Bullets designed for hunting typically feature a soft point or hollow point, which expands upon impact, creating a larger wound channel. Bullets designed for target shooting are often boat-tail designs, which improve ballistic coefficient and accuracy.

Choosing the Right Bullet for Hunting

When choosing a bullet for hunting, consider the size of the game you’re hunting, the range at which you’ll be shooting, and the terrain. For large game like elk and moose, the 308 180-grain bullet is a solid choice due to its excellent penetration. For medium-sized game like deer and antelope, the 308 168-grain bullet can be effective, especially at longer ranges. In areas with heavy cover, the heavier bullet may be less likely to be deflected by brush.

Selecting the Best Bullet for Target Shooting

For target shooting, accuracy is paramount. The 308 168-grain bullet is a popular choice among target shooters due to its inherent accuracy and flatter trajectory. It’s also easier to manage recoil, allowing for faster follow-up shots. When selecting a bullet for target shooting, consider the distance you’ll be shooting and the ballistic coefficient of the bullet. A higher ballistic coefficient will result in less wind drift and a flatter trajectory at longer distances.
