Quick Answer
For hunting elk with a chassis rifle, the best caliber is typically a high-velocity cartridge in the 6.5mm or 7mm range, such as the 6.5 Creedmoor or 7mm Remington Magnum. These calibers offer a good balance of kinetic energy and bullet expansion for efficient elk killing. A minimum of 2,000 ft-lbs of kinetic energy is recommended for a clean kill.
Caliber Options for Chassis Rifles
When choosing a caliber for your chassis rifle, consider the kinetic energy required for a clean elk kill. The 6.5mm Creedmoor is a popular choice, offering a velocity of approximately 2,750 ft/s with a 130-grain bullet and 2,330 ft-lbs of kinetic energy. This makes it an excellent option for elk hunting. The 7mm Remington Magnum, on the other hand, offers a slightly higher kinetic energy of 2,600 ft-lbs with a 150-grain bullet at 2,970 ft/s.
Ballistic Performance and Chassis Rifle Stability
Chassis rifles are designed to provide exceptional stability and accuracy, making them ideal for long-range shooting. When paired with a high-velocity cartridge like the 6.5 Creedmoor or 7mm Remington Magnum, the chassis rifle becomes a formidable hunting platform. To maximize ballistic performance, consider using a 24- or 26-inch barrel to maintain velocity and minimize bullet drop at longer ranges.
Load Selection and Bullet Choice
When selecting a load for your chassis rifle, consider the specific elk hunting scenario and the terrain you’ll be hunting in. For example, a 130-grain bullet with a high ballistic coefficient may be ideal for long-range shots, while a heavier 150-grain bullet may be more effective at closer ranges. Always choose a load with a suitable expansion profile and velocity to ensure a clean and humane elk kill.
