La 6,5x57R cartridge has stood the test of time, remaining a functional choice even in a market increasingly dominated by modern innovations. It’s not just nostalgia for the past, but an appreciation of how this historic round, like many others, compares to newer offerings, often introduced by American manufacturers to stimulate the market. In the United States, the 6,5 mm caliber, also called .264”, has seen a resurgence thanks to several new cartridges, even though many of them are not entirely new in concept.
Already in the 50s, Winchester introduced the .264 Win. Mag., an excellent cartridge but overshadowed by the subsequent 7 Rem. Mag. In Europe, however, the 6,5 mm caliber had already been chosen at the end of the nineteenth century for various military studies, with Mauser developing several proposals, such as the 6,5×55 SM, still used for military and hunting purposes. Among these, the 6,5×57 stands out, never officially adopted by the armed forces, but very popular for hunting throughout Europe.
The ballistic characteristics of the 6,5x57R
The 6,5x57R, with a short rifling ratio of 8 to 8,5:1, supports a wide range of bullet weights, from 6 to 10 grams. The lighter bullets, with a pointed nose, offer a muzzle velocity (V/0) of 1000 m/s, ideal for chamois hunting, while the heavier ones, such as the rounded cylindrical bullet, were used to hunt deer at shorter ranges.
Today, bullets weighing between 8 and 9 grams represent the right compromise, such as the RWS 6,5x57R with KS (Kegel Spitze) bullet, which guarantees high precision and damage on game such as roe deer. For thicker-skinned game, such as wild boar, the variant with 9,1 g DK (Doppel Kern) bullet is available, which offers greater penetration capacity.
Compatible weapons and practical use
Over the years, the rifle version of the 6,5x57R has lost ground, while the collared variant has remained a consolidated choice for break-action shotguns, such as drillings or kipplaufs. In the latter, the cartridge is often associated with 12 or 16 gauges. Among the most recent guns that support this cartridge, the Rizzini KR1 and the Sabatti SKL stand out, both successfully tested on roe deer and wild boar using different bullet configurations.
The packaging and performance of the RWS 6,5x57R
RWS presents this cartridge in a rustically designed package with a brown and black cardboard box and a transparent window. The cartridge and bullet specifications, such as weight and caliber, are clearly marked, along with the safety regulations and ballistic performance. The KS bullet, with tombac jacket and hardened lead core, offers a good combination of accuracy and penetration.
Ballistic performance, measured with a 600 mm barrel, shows a muzzle velocity of 800 m/s, which progressively decreases to 574 m/s at 300 m. Energy varies from 2624 to 1351 Joules, with the GEE set at 164 m and satisfactory results up to 210 meters. Despite slight variations compared to previous versions of the same cartridge, the 6,5x57R with KS bullet remains an effective option for hunting at medium ranges.
In summary, despite technological evolution and the decrease in current offerings, the RWS 6,5x57R cartridge continues to represent a solid choice for those who appreciate European ballistic traditions, while offering modern performance sufficient for a wide range of game.
