6.5x55mm Swedish Mauser: A Comprehensive Overview

The 6.5x55mm Swedish Mauser, also known as the 6.5x55 Swedish or 6.5x55 Scan, is a rifle cartridge developed in 1891 for use in the Swedish Mauser rifle. Known for its exceptional accuracy, mild recoil, and long-range capabilities, this cartridge has gained popularity among hunters and target shooters worldwide. Its versatility and effectiveness have made it a favorite for both military and civilian applications, particularly in Scandinavian countries.

History and Development

The 6.5x55mm Swedish Mauser was jointly developed by Sweden and Norway in 1891 for their new service rifles. It was officially adopted by both countries in 1894, with Sweden using it in their m/94 carbine and m/96 rifle, while Norway chambered it in their Krag-Jørgensen rifles.

The cartridge was designed to provide a balance between power, accuracy, and manageable recoil. Its 6.5mm bullet diameter was chosen for its high sectional density, which contributes to excellent penetration and retained energy at long ranges. The case design allowed for efficient powder burn and consistent performance.

Throughout its service life, the 6.5x55mm proved to be an effective military cartridge. It saw use in both World Wars and continued to be used by Swedish Home Guard units until the 1990s. The cartridge's long-range accuracy made it particularly suitable for designated marksman roles.

In the civilian market, the 6.5x55mm gained popularity as a hunting cartridge, especially in Scandinavia. Its combination of flat trajectory, mild recoil, and excellent terminal performance on medium-sized game made it a favorite among hunters. The cartridge's accuracy also attracted the attention of target shooters, leading to its use in various competitive shooting disciplines.

Today, the 6.5x55mm remains popular among hunters and target shooters worldwide. Modern ammunition manufacturers offer a wide range of loads, from light target bullets to heavy hunting projectiles, catering to various shooting applications. The cartridge's enduring popularity has also led to the development of modern rifles chambered for this classic round, ensuring its continued relevance in the 21st century.
