The 6.5x55mm Swedish Mauser: A Cartridge Steeped in History
The 6.5x55mm Swedish Mauser, often simply referred to as the 6.5 Mauser, is a cartridge with a rich history dating back to the late 19th century. Adopted by the Swedish and Norwegian militaries in 1894, it was designed to provide a flat trajectory, good penetration, and manageable recoil. Unlike some cartridges designed purely for military use and quickly replaced, the 6.5x55mm gained a loyal following among hunters and target shooters, a testament to its inherent accuracy and effectiveness.
The cartridge’s origins are intertwined with the development of smokeless powder. Prior to its adoption, black powder cartridges were the norm, producing significant smoke and fouling. The advent of smokeless powder allowed for higher velocities, flatter trajectories, and improved accuracy. The 6.5x55mm was designed from the outset to take advantage of these advancements, resulting in a cartridge that was ahead of its time.
One of the key design features of the 6.5x55mm is its relatively long, slender bullet. This high sectional density, combined with a moderate velocity, allows for excellent penetration on game animals. The cartridge also exhibits a relatively flat trajectory, making it easier to hit targets at longer ranges. Furthermore, the 6.5x55mm is known for its inherent accuracy, a trait that has made it a favorite among competitive shooters.
Understanding the Dimensions and Specifications
To truly understand the 6.5 Mauser what caliber entails, it’s essential to delve into its specific dimensions and specifications. The “6.5” in the name refers to the bullet diameter, which is approximately 6.72 mm or .264 inches. The “55” refers to the case length, which is 55 millimeters. These dimensions, combined with other factors such as case capacity and shoulder angle, contribute to the cartridge’s overall performance characteristics.
Key specifications of the 6.5x55mm Swedish Mauser include:
- Bullet Diameter: 0.264 inches (6.72 mm)
- Case Length: 2.165 inches (55 mm)
- Overall Length: 3.150 inches (80 mm)
- Primer Type: Large Rifle
- Typical Bullet Weights: 120 grains to 160 grains
It’s important to note that while the 6.5x55mm is often referred to as the “6.5 Mauser,” it’s crucial to differentiate it from other 6.5mm cartridges. The 6.5 Creedmoor, for example, is a more modern cartridge that offers similar performance characteristics in a shorter action rifle. However, the 6.5x55mm remains a distinct and highly capable cartridge in its own right.
The Performance and Ballistics of the 6.5x55mm
The 6.5x55mm is renowned for its balanced performance, offering a blend of manageable recoil, flat trajectory, and excellent terminal ballistics. When loaded with appropriate bullets, it’s a capable cartridge for a wide range of game animals, from deer and antelope to elk and even moose. Its inherent accuracy also makes it a popular choice for target shooting and competitive shooting disciplines.
The ballistics of the 6.5x55mm are influenced by several factors, including bullet weight, bullet design, and powder charge. Generally, heavier bullets offer better penetration, while lighter bullets offer flatter trajectories. A 140-grain bullet, for example, is a popular choice for hunting medium-sized game, providing a good balance of penetration and trajectory. With a 140 grain bullet, muzzle velocities typically range from 2600 to 2800 feet per second.
Ballistic coefficients also play a significant role in the cartridge’s performance. Bullets with higher ballistic coefficients retain velocity better and are less affected by wind drift. This is particularly important for long-range shooting, where even slight errors in wind estimation can significantly impact accuracy.
In our experience, the 6.5x55mm offers a very forgiving recoil, making it a great choice for shooters of all sizes and skill levels. This allows for more comfortable shooting sessions and improved accuracy, especially during rapid follow-up shots.
Rifles Chambered in 6.5x55mm: A Legacy of Quality

Its balanced performance, manageable recoil, and excellent penetration make it a popular choice among hunters around the world. It is generally considered suitable for anything up to and including elk and moose, provided appropriate bullets are used and shots are carefully placed.
When hunting with the 6.5x55mm, it’s crucial to select the appropriate bullet for the game being hunted. For deer and antelope, a 120-grain to 140-grain bullet is generally recommended. For larger game animals such as elk and moose, a heavier bullet in the 156-grain to 160-grain range is preferred. It’s also important to choose a bullet with a design that promotes controlled expansion and deep penetration.
Shot placement is also critical when hunting with the 6.5x55mm. Like any cartridge, it’s essential to aim for vital areas such as the heart and lungs. With proper shot placement, the 6.5x55mm is capable of delivering quick and humane kills on a wide range of game animals.
Reloading the 6.5x55mm: Tailoring Performance to Your Needs
One of the advantages of the 6.5x55mm Swedish Mauser is that it’s a relatively easy cartridge to reload. Reloading allows shooters to tailor the performance of the cartridge to their specific needs and preferences. It also offers the opportunity to experiment with different bullet weights, bullet designs, and powder charges to achieve optimal accuracy and performance.
When reloading the 6.5x55mm, it’s essential to follow established reloading data and safety procedures.
