Quick Answer
For .308 varmint hunting, the best grains are 55-70 grains, offering a balance of velocity and kinetic energy transfer, making them suitable for small to medium-sized varmints, including coyotes, bobcats, and jackrabbits.
Grain Selection for Varmint Hunting
When selecting grains for .308 varmint hunting, it’s essential to consider the optimal weight range, which typically falls between 55-70 grains. This weight range provides a suitable balance between velocity and kinetic energy transfer, making it effective for small to medium-sized varmints. For instance, the Hornady 55-grain SST and the Winchester 68-grain Power Point are two popular choices, offering reliable expansion and deep penetration.
Velocity and Kinetic Energy
The .308 Winchester cartridge is known for its flat-shooting capabilities, making it an excellent choice for varmint hunting at longer ranges. To maximize kinetic energy transfer, it’s crucial to select a grain weight that offers sufficient velocity, typically around 2,800-3,000 feet per second. This range allows for effective expansion and penetration, taking down varmints quickly and humanely. When using heavier grains, such as the 68-grain Power Point, aim for a slightly lower velocity to prevent over-expansion and reduced penetration.
Bullet Type and Construction
When choosing varmint bullets, consider the type of construction and intended use. For example, the Hornady SST features a sleek, aerodynamic profile and a secure locking ring, ensuring consistent expansion and deep penetration. In contrast, the Winchester Power Point features a soft, lead-free construction, ideal for hunting in areas where lead is prohibited. When selecting varmint bullets, consider the specific needs of your hunt and the characteristics of the target animal.
