6.5 x 55 Swedish Load Data

The 6.5 x 55 Swedish (commonly called 6.5x55mm or 6.5 Swedish Mauser) has a storied history that dates to the late 19th century, developed jointly by Sweden and Norway as a military cartridge that balanced accuracy, manageable recoil, and effective terminal performance. Adopted in 1894, it served in military service for decades in Mauser-pattern rifles and later in a broad array of civilian sporting arms. Its long, slender case and 6.5mm bullet diameter established an early reputation for excellent sectional density and ballistic efficiency, traits that made the round a favorite among precision shooters and hunters as military use waned. Over time the cartridge evolved from service ammunition into a beloved sporting round across Scandinavia, the British Isles, and North America, underpinning both match-grade target use and large-game hunting traditions.

As an applications-focused round, the 6.5x55 Swedish is extremely versatile. It is prized by reloaders for predictable accuracy in bolt-action rifles, for use in long-range target shooting, and for field hunting where low recoil and high ballistic coefficients matter. The cartridge performs well in target, precision, and hunting roles: it’s accurate enough for benchrest-style groups and F-class shooting while retaining hunting power for medium and many large game species at realistic ranges. Reloaders appreciate the round’s forgiving pressure window and the ability to tailor loads for particular rifles and bullet types, making it a popular choice for anyone seeking a do-it-all 6.5 cartridge with a long history of consistent performance.

Target species for the 6.5x55 Swedish range from deer-sized animals up to the largest European game when properly paced and delivered. In North America and Europe it is commonly used on whitetail and roe deer, red stag, and, when employing heavier bullets and proper shot placement, on elk and moose in many conditions. Its combination of high sectional density and decent retained energy, especially with modern high-BC 6.5mm projectiles, gives it an edge for long shots on medium-sized game. For varmint control it is capable but generally overbore; reloaders hunting smaller game will often choose lighter bullets for flatter trajectories and reduced meat damage.

Typical bullet weights and caliber characteristics are central to why reloaders favor the 6.5x55. Common bullet weights span roughly 120 to 160 grains, with many shooters favoring mid-range 120–140-grain bullets for a balance of trajectory and energy; heavier 140–160-grain bullets are popular for large game and long-range stability. The cartridge’s inherent high sectional density and usually modest muzzle report combine with a relatively mild recoil impulse, enabling precise shot placement. Rifles chambered in 6.5x55 often feature medium-slow twist rates that stabilize modern high-BC bullets well. Brass availability and case geometry make it amenable to careful handloading: consistent neck dimensions, a long neck for good bullet-seating concentricity, and widespread factory brass supplies contribute to its enduring popularity among reloaders who value accuracy, economy, and a cartridge well-suited to both target and game.
