The Swedish Mauser 6.5x55, often referred to as the 6.5x55 Swedish or simply the Swedish Mauser, is more than just a rifle cartridge; it's a piece of firearms history. This powerful and accurate round, chambered in iconic bolt-action rifles, has a rich legacy spanning over a century, captivating shooters and collectors alike. This article will delve into the fascinating history, technical specifications, ballistics, and enduring popularity of the 6.5x55 Swedish.
The Genesis of a Legend: History and Development
The 6.5x55 Swedish cartridge emerged in the late 19th century, a product of the Swedish military's desire for a superior service cartridge. Developed by Carl Gustafs Stads Gevärsfaktori (CGF), the state-owned arms factory, it replaced the earlier 8x58R round. The driving force behind the change was a desire for increased range and accuracy while minimizing recoil, characteristics that ultimately shaped the 6.5x55's design and enduring reputation.
The adoption of smaller-caliber, higher-velocity rounds was a significant trend in military circles at the time. The 6.5x55 represented a significant leap forward, offering flatter trajectory and improved penetration compared to its larger-caliber predecessors. This technological advancement cemented its role as a highly effective military cartridge for decades. The round's reputation for accuracy and effectiveness even led to its adoption by other nations, solidifying its place in firearms history.
Key Features Driving its Success:
- High Velocity: The 6.5x55 Swedish is known for its relatively high muzzle velocity, contributing significantly to its long range and flat trajectory.
- Accuracy: The cartridge's design lends itself to exceptional accuracy, a feature highly valued in both military and sporting applications.
- Low Recoil: Compared to larger-caliber rounds, the 6.5x55 offers noticeably reduced recoil, enhancing shooter comfort and control during extended shooting sessions.
- Excellent Ballistics: The combination of velocity and weight leads to superior downrange energy and penetration. The bullet's design further enhances penetration and accuracy.
Technical Specifications of the 6.5x55 Swedish Cartridge
The 6.5x55 Swedish cartridge boasts several key technical specifications that define its performance and characteristics.
| Specification | Value |
|---|---|
| Case Type | Bottleneck |
| Caliber | 6.5mm (.264 inch) |
| Case Length | 55mm (2.165 inches) |
| Bullet Weight (common) | 140-160 grains |
| Muzzle Velocity (typical) | 2,600 - 2,800 fps (depending on load) |
| Maximum Range | Over 3,000 yards (practical range is significantly shorter due to bullet drop) |
Ballistics and Performance
The 6.5x55's ballistics are a testament to its effective design. The high muzzle velocity results in a flat trajectory, meaning less bullet drop at longer ranges. This feature, combined with its inherent accuracy, makes the 6.5x55 exceptionally suitable for long-range shooting.
Comparative Ballistics Table (approximate values):
| Cartridge | Muzzle Velocity (fps) | Muzzle Energy (ft-lbs) |
|---|---|---|
| 6.5x55 Swedish | 2,700 | 2,200 |
| .30-06 Springfield | 2,800 | 2,700 |
| 7mm Rem Mag | 3,000 | 3,000 |
(Note: Ballistic performance varies significantly depending on ammunition manufacturer and load.)
It's crucial to note that while the 6.5x55's maximum range is extensive, practical shooting engagements are limited by factors like windage, bullet drop and sight limitations. Effective range in practical hunting or target shooting will generally fall far below maximum range.
