April 5, 2026

Quick Answer

The 6.5x55 Swedish cartridge has historical significance as a versatile and effective hunting caliber that originated in Sweden in the late 19th century, known for its accuracy and flat trajectory, making it well-suited for hunting large game such as moose.

Origins and Design

The 6.5x55 Swedish cartridge was introduced in 1894 and was designed by Swedish rifle manufacturer, Carl Gustaf, in collaboration with the Swedish Army. The cartridge’s unique combination of a 6.5mm bullet diameter and a 55mm case length provided an optimal balance between expansion and penetration. This design allowed the cartridge to be effective at both close and long ranges, making it a popular choice for hunting.

Performance and Ballistics

The 6.5x55 Swedish cartridge is capable of delivering impressive ballistics, with a muzzle velocity of approximately 2,400 feet per second and a bullet weight of around 140 grains. At 500 yards, the cartridge’s trajectory remains relatively flat, with a drop of only about 14 inches below the point of aim. This makes it an ideal choice for hunting large game, such as moose, at longer ranges.

Hunting Applications

The 6.5x55 Swedish cartridge has become a popular choice for hunting moose in Sweden and other parts of Northern Europe due to its excellent accuracy and penetration capabilities. When paired with a suitable rifle, such as the Carl Gustaf M/96, the cartridge can deliver a one-shot kill at ranges of up to 400 yards. Experienced hunters often choose this caliber for its reliability and effectiveness in hunting large, powerful game.
