Have elk hunters switched from .270 to other calibers — why?

Choosing the Right Caliber

Elk hunters often face larger and more aggressive animals, requiring a more potent cartridge. Calibers such as the 7mm Remington Magnum (.284" bullets) and .300 Winchester Magnum (.308" bullets) offer significant advantages in terms of kinetic energy and bullet expansion. These cartridges deliver enough energy to consistently make one-shot kills on larger elk. The 7mm Remington Magnum, for example, offers around 2,900 ft-lbs of energy at 500 yards, which is roughly 500 ft-lbs more than the .270 Winchester.

Ballistic Performance Comparison

When comparing the .270 Winchester to the 7mm Remington Magnum, it’s essential to consider the ballistic performance of each cartridge. The 7mm Remington Magnum has a flatter trajectory and better wind resistance due to its heavier bullets and longer case length. At longer ranges, the 7mm Remington Magnum’s heavier bullets also retain more kinetic energy, resulting in a more devastating impact. In contrast, the .270 Winchester’s lighter bullets tend to lose energy more quickly and may not provide a one-shot kill. While the .270 is a capable cartridge, its limitations at longer ranges make the 7mm Remington Magnum a more popular choice for elk hunters.

Hunting and Load Considerations

When selecting a caliber for elk hunting, it’s essential to consider the specific needs of the hunt. For example, those hunting in areas with dense vegetation or at longer ranges may prefer the 7mm Remington Magnum’s heavier bullets and flatter trajectory. In contrast, those hunting in more open terrain or at closer ranges may be satisfied with the .270 Winchester’s lighter bullets. In terms of load selection, elk hunters often opt for bullets with a minimum weight of 150 grains and a bullet diameter of .284" or greater. The most popular bullets for elk hunting include the 150-grain and 180-grain options from manufacturers such as Barnes and Nosler.
