Choosing the right caliber for your hunting or shooting endeavors can be a daunting task. With the plethora of options available, it’s essential to understand the nuances between popular calibers like the 7mm Remington Magnum and the .308 Winchester (commonly known as 308). In this comprehensive guide, we’ll walk through the differences, similarities, and considerations between these two widely used cartridges.

Introduction to 7mm Rem Mag VS 308

Before delving into the specifics, let’s get acquainted with our contenders.

7mm Remington Magnum

7mm rem mag

The 7mm Remington Magnum, often referred to as 7mm Rem Mag, is a powerful and versatile cartridge developed in the early 1960s. Known for its flat trajectory and long-range capabilities, it has gained popularity among hunters and long-range shooters alike.

.308 Winchester (308)

The .308 Winchester, or simply 308, is a well-established cartridge with a rich history dating back to the 1950s. Renowned for its accuracy, moderate recoil, and versatility, the 308 is a favorite among hunters, competitive shooters, and military snipers.

Now that we’ve introduced our contenders, let’s dive into a detailed comparison.

Ballistics and Performance

Recoil: 308 vs 7mm rem mag

7mm Rem Mag vs 308 Recoil is a crucial factor to consider, particularly for shooters who prioritize comfort and follow-up shot accuracy. The 7mm Rem Mag typically generates more recoil than the 308, owing to its larger case capacity and higher velocity. However, this increased recoil is often manageable with proper shooting techniques and recoil mitigation devices.

Trajectory and Long-Range Performance

When it comes to long-range shooting, the 7mm Rem Mag holds a slight advantage over the 308. With its higher muzzle velocity and superior ballistic coefficients, the 7mm Rem Mag exhibits flatter trajectories and retains energy better at extended ranges. This makes it a preferred choice for hunting larger game at longer distances.

Hunting Applications

Both the 7mm Rem Mag and the 308 are capable hunting cartridges, but their ideal applications may vary.

7mm Rem Mag for Hunting

The 7mm Rem Mag shines when hunting medium to large game at extended ranges. Its high velocity and energy delivery make it suitable for hunting elk, moose, and deer in open terrain where shots may be taken at considerable distances.

308 for Hunting

308 Mag

The 308, with its moderate recoil and excellent accuracy, is a versatile choice for hunting various game species, including deer, hogs, and even elk. Its effectiveness at moderate ranges and wide availability of ammunition makes it a reliable option for hunters in diverse environments.

Comparing Other Calibers

270 Weatherby vs 7mm Rem Mag

270 Weatherby

While both the 270 Weatherby and the 7mm Rem Mag are capable cartridges, they differ in terms of velocity, trajectory, and recoil. The 270 Weatherby typically offers higher velocities and flatter trajectories compared to the 7mm Rem Mag, but it may come with increased recoil and ammunition costs.

7MM Rem Mag vs 7mm Weatherby mag

The 7mm Weatherby Magnum shares similarities with the 7mm Rem Mag in terms of bullet diameter and performance. However, due to its larger case capacity, the Weatherby variant may offer slightly higher velocities and flatter trajectories.

6.5-300 Weatherby

The 6.5-300 Weatherby Magnum is a high-performance cartridge known for its exceptional velocity and flat trajectory. While it excels in long-range shooting, its recoil and barrel wear may be significant factors to consider for shooters.

Technical Considerations

Barrel Life and Powder Selection

The 7mm rem mag barrel life of a rifle chambered in 7mm Rem Mag can vary depending on factors such as shooting frequency, barrel quality, and maintenance practices. To prolong barrel life, selecting appropriate powders that balance velocity and barrel wear is crucial.

Twist Rate and Ammunition Selection

The twist rate of a rifle barrel influences the stability of the bullet in flight, especially for lengthier and heavier projectiles. A 1 in 10 twist 308 rate is commonly recommended for .308 rifles, while the optimal twist rate for 7mm Rem Mag rifles may vary based on bullet weight and design.

Popular Comparisons and Alternatives

Nosler 28 vs 7mm Rem Mag

The Nosler 28, based on the 7mm Rem Mag case, offers similar ballistic performance with potential improvements in accuracy and terminal ballistics. However, its availability and cost may influence shooters’ preferences.

7mm RUM vs 7mm Rem Mag

The 7mm Remington Ultra Magnum (RUM) delivers higher velocities and energy compared to the 7mm Rem Mag but comes with increased recoil and ammunition costs. Shooters must weigh these factors against their intended applications and shooting preferences.


In the debate between the 7mm Rem Mag and the 308, there is no clear winner. Each cartridge offers distinct advantages and limitations, catering to different shooting disciplines and preferences. Whether you prioritize long-range performance, manageable recoil, or versatility, best powder for 7mm rem mag, understanding the characteristics and applications of each cartridge is essential in making an informed decision.

Ultimately, the best cartridge for you depends on your specific needs, shooting style, and intended use. So, take your time, do your research, and consider factors such as recoil, trajectory, best 308 round for elk, hunting applications, and technical considerations before making your choice. Happy shooting!

In the dynamic world of firearms and ammunition, the debate between the 308 win vs 7mm rem mag is just one of many discussions that fuel the passion of shooters and hunters worldwide. As technology advances and preferences evolve, new cartridges and calibers will continue to emerge, offering shooters even more choices and opportunities to explore.
