6.5 x 55 Swedish Ladedata

The 6.5 x 55 Swedish Mauser cartridge, often referred to as the 6.5 Swede, was developed in 1891 by a joint Swedish-Norwegian commission seeking a powerful and accurate round for their military forces. This cartridge gained prominence through its use in the Swedish Mauser rifles and various Norwegian firearms, earning a solid reputation for excellent accuracy and manageable recoil.

Technically, the 6.5 x 55 features a rimless bottleneck case with a relatively large case capacity that supports efficient combustion and consistent ballistic performance. The original military specification used a 156-grain round-nosed bullet, but modern applications predominantly employ lighter projectiles, typically ranging from 120 to 140 grains. These bullets benefit from high sectional density and are well-suited for deep penetration, making them ideal for both target shooting and hunting.

The cartridge's ballistic performance is distinguished by its flatter trajectory and stable flight characteristics. Muzzle velocities for the 6.5 x 55 can range from approximately 2600 to 2900 feet per second, depending on the bullet weight and powder load, providing excellent precision for long-range shooting.

In practical applications, the 6.5 x 55 Swedish excels in hunting medium-sized game such as deer and boar, owing to its effective energy transfer and minimal recoil. It is also a popular choice among target shooters and competitive marksmen in disciplines such as benchrest and precision rifle competitions.

For reloaders, the 6.5 x 55 offers significant versatility. Its moderate pressures and broad selection of bullets and powders allow for custom tailoring of loads to specific needs, whether optimizing accuracy or enhancing terminal performance. The ease of finding high-quality components makes it a flexible and rewarding cartridge for those who seek both performance and precision.
