6.5 x 55 Swedish Ladddata

The 6.5 x 55 Swedish, also known as 6.5 x 55mm SE or simply "Swedish Mauser," was developed in 1891 for the Swedish and Norwegian military. Admired for its balanced blend of accuracy and ballistic efficiency, this cartridge has become a favorite among hunters, sport shooters, and competition marksmen. Its long, slender bullets offer exceptional aerodynamic properties, lending to its renowned long-range performance.

Technical characteristics of the 6.5 x 55mm include a bullet diameter of .264 inches (6.7 mm) and a case length of 55 mm. The cartridge case is rimless, bottlenecked, with a relatively moderate operating pressure, facilitating safe use in a variety of rifle actions, including older military surplus arms.

Ballistic performance is a key appeal of this cartridge, capable of driving bullets at moderate velocities with manageable recoil. Typical bullet weights range from 120 to 160 grains. A popular choice for hunters is the 140-grain bullet, which offers an excellent balance of velocity and terminal performance on medium to large game. Muzzle velocities range around 2,600 to 2,850 feet per second, depending on bullet weight and powder charge.

For the reloader, the 6.5 x 55 Swedish offers the advantage of a high case volume relative to the diameter of its bullets, allowing for flexibility in selecting powders and achieving desired performance levels. Moreover, the cartridge's inherent accuracy makes it highly rewarding for precision reloaders who wish to fine-tune loads for specific rifles or applications. Its mild recoil and consistent ballistics make it suitable for both hunting and competitive settings, ensuring its continued popularity and utility.
