Quick Answer
A 7mm SAUM elk load should be weighed between 75 and 85 grains, depending on the specific case and bullet combination, with a target of 80 grains for optimal performance.
Case Capacity and Bullet Selection
When selecting a 7mm SAUM elk load, it’s essential to understand the case capacity and bullet selection. The 7mm SAUM case has a larger capacity than the 7mm Remington Magnum, allowing for a heavier bullet or more powder. A 120- to 130-grain bullet is a good starting point, but for elk hunting, a heavier bullet is often preferred. Look for bullets like the Berger 160-grain Elite Hunter or the Nosler 150-grain AccuBond.
Powder Charge and Load Development
To achieve optimal performance, the powder charge for a 7mm SAUM elk load should be in the 80- to 85-grain range. For a 120-grain bullet, start with a load of 80.5 grains of H4831 or RL22. For a 160-grain bullet, start with a load of 82.5 grains of H4831 or RL22. Use a load development process, such as the Lyman Reloading Handbook or the Hornady Loading Manual, to determine the optimal powder charge for your specific load. Always start with a low charge and work up to avoid over-pressure.
Muzzle Velocity and Kinetic Energy
A 7mm SAUM elk load should have a muzzle velocity of at least 2,900 feet per second (fps) to deliver optimal kinetic energy. With the right bullet and powder combination, a 7mm SAUM elk load can achieve this velocity while delivering a flat, long-range trajectory. A muzzle velocity of 2,900 fps will result in a kinetic energy of approximately 1,400 foot-pounds (ft-lbs), which is sufficient for elk hunting.
