Comparing .30-06 Springfield With .308 Win For Elk?

Ballistic Comparison

When comparing the two cartridges, the .30-06 Springfield offers approximately 300-400 more foot-pounds of energy than the .308 Winchester at 100 yards. However, the difference is relatively minor at longer ranges, and both cartridges are well-suited for elk hunting. For example, the .30-06 Springfield with a 150-grain bullet fired from a 2.5-inch twist barrel will reach a velocity of approximately 2,850 feet per second, while the .308 Winchester with the same bullet fired from the same barrel will reach a velocity of approximately 2,750 feet per second.

Real-World Performance

In real-world hunting scenarios, both cartridges have proven effective for elk hunting. However, the .30-06 Springfield has a slight edge when hunting larger bulls or at longer ranges. This is due in part to its slightly greater kinetic energy, but also to its slightly better penetration. For example, a study by the Boone and Crockett Club found that .30-06 Springfield rifles were used in over 40% of all elk kills in the western United States between 2000 and 2010. In contrast, .308 Winchester rifles were used in around 20% of all elk kills during the same period.

Rifle and Ammunition Selection

When selecting a rifle and ammunition for elk hunting, it’s essential to choose a combination that is well-suited to the task at hand. In general, a rifle with a minimum of a 2.5-inch twist barrel is recommended for elk hunting, as this will help to stabilize heavier bullets and ensure accurate shot placement. Ammunition selection is also critical, with 150- to 165-grain bullets being the most popular choices for elk hunting. These bullets offer a good balance between expansion and penetration, and are well-suited for hunting larger elk.
