Pros and cons of using heavier bullets in 7mm SAUM?

Increased Penetration

Heavier bullets in the 7mm SAUM can be effective for hunting large game like elk, where deep penetration is crucial. For example, a 150-grain bullet may not be as effective as a 175-grain bullet at longer ranges or when shooting at larger animals. The added weight provides more kinetic energy, which translates to deeper penetration and potentially larger wound channels.

Reduced Velocity and Increased Recoil

However, using heavier bullets in the 7mm SAUM can compromise the cartridge’s velocity and accuracy. The 7mm SAUM is a high-pressure cartridge, and adding too much weight to the bullet can cause the velocity to drop off significantly. For instance, a 175-grain bullet at 3,000 feet per second (fps) may only achieve 2,800 fps with a 180-grain bullet. This reduction in velocity can also result in increased recoil, making the rifle less manageable for some shooters.

Practical Considerations

When choosing between different bullet weights in the 7mm SAUM, it’s essential to consider the intended use, the shooter’s skill level, and the cartridge’s capabilities. Aiming for a balance between penetration and velocity is crucial. A 170-grain bullet at 3,000 fps may be a more practical choice for elk hunting, as it offers a good balance between penetration and velocity, while minimizing recoil and reducing the risk of over-penetration.
