The 8x65mm RS cartridge is a classic European hunting round, developed in the early 20th century to answer the demand for a powerful, rimmed case suitable for break-action rifles and combination guns. Originating in Germany, the 8x65 RS was designed to offer improved ballistic performance over the widely popular 8x57JRS. The slightly lengthened case capacity translates into higher velocity and energy, making it particularly attractive for hunters looking to extend their effective range. Its rimmed design, denoted by the “RS” (Rand Spitzer), facilitates extraction and reliability in break-open rifles, which were popular throughout central Europe at the time and remain so among traditionalists and stalking hunters. The cartridge quickly earned a reputation for dependable performance, and its legacy continues decades later among discerning reloaders and enthusiasts.
Today, the 8x65 RS finds its applications predominantly in hunting medium-sized to large game across Europe and, to a lesser extent, in Africa. Its balanced combination of velocity and bullet mass provides the knockdown power needed for wild boar, red deer, and similarly sized game. The cartridge’s design ensures reliable functioning in double rifles and combination guns, a feature especially valued by hunters who operate in challenging environments or who require utmost dependability in their field equipment. While not as common as some other European calibers, the 8x65 RS stands out for its consistent accuracy and respectable trajectory, making it suitable for open landscapes as well as forested terrain.
Regarding target species, the 8x65 RS excels against European wild boar, roe deer, red deer, and even sika deer. Its power places it on par with or slightly above the classic 8x57JRS, allowing confident shots at longer distances or when extra penetration is required. Some hunters have also employed it for moose in Scandinavia, and those with access to African hunting grounds have found its ballistics satisfactory for antelope and similarly sized game. The cartridge’s flexibility makes it a top choice for those who appreciate having one rifle to handle a range of hunting scenarios.
For reloaders, the 8x65 RS offers a range of bullet weights commonly from 180 to 220 grains (approximately 11.7 to 14.3 grams), with both soft-point and bonded designs popular for optimizing terminal performance on larger game. Its case is slightly longer than the 8x57, which allows for increased powder capacity and, consequently, higher velocities while maintaining safe pressures in strong, modern break-action rifles. The caliber utilizes a standard 8mm (.323”/8.2mm) diameter bullet, which means a wide variety of commercial bullet types are available. Its moderate recoil and efficient case design also contribute to a pleasant shooting experience, making follow-up shots quick and manageable, an asset when hunting game in dense cover.
Overall, the 8x65 RS remains a venerable and well-rounded choice for reloaders seeking a potent and versatile rimmed cartridge. Although it may not enjoy the same widespread commercial support as some modern magnums, its enduring popularity among experienced hunters and traditionalists is a testament to its balanced performance, reliability, and historical significance. For those able to source quality brass and components, the 8x65 RS promises rewarding results in the field and at the reloading bench alike.
