6 x 47 SM

The 6x47 Swiss Match (often abbreviated as 6x47 SM) is a cartridge that emerged from Switzerland in the late 1990s, specifically for target shooting disciplines that demand precision and consistency. Developed by the renowned Swiss manufacturer RUAG, the 6x47 SM was engineered to provide shooters with a low-recoil alternative to larger calibers, without sacrificing downrange accuracy or performance. Its parent case is the legendary 6.5x47 Lapua, necked down to accept 6mm bullets, which instantly granted the 6x47 SM a reputation for exceptional accuracy and versatility. Over time, this cartridge gained strong support among European and American competitive shooters, particularly in F-Class and benchrest circles, due to its impressive track record in 300-meter ISSF and CISM rifle competitions.

The 6x47 SM quickly carved its niche within the realm of competitive shooting, as its design allows for superb performance in high-precision applications such as benchrest, F-Class, and PRS (Precision Rifle Series) matches. Its mild recoil relative to larger cartridges makes it easier for competitors to stay on target between shots, an advantage that’s particularly valuable in rapid-fire or positional shooting stages. The inherent consistency and small standard deviation in velocity appeal to reloaders aiming for peak accuracy. Over the years, the 6x47 SM has also seen limited use in varmint and medium game hunting, but its primary strength remains in target applications, where tight groups and minimal wind drift are mandatory for success.

For hunting use, the 6x47 SM is best suited for smaller to medium-sized game, such as varmints, marmots, foxes, and even roe deer, where precision shot placement is prioritized over brute stopping power. Reloaders appreciate the flat trajectory and minimal recoil, which allow for quick follow-up shots and a gentle learning curve for newer shooters. Its terminal ballistics make it a marginal choice for larger species like wild boar or red deer unless ideal conditions and premium bullets are used. Most users, however, regard it as a purpose-built competition or varmint round rather than a big game option.

The 6x47 SM typically accommodates bullet weights between 90 and 115 grains, with 105- and 107-grain match bullets from makers like Hornady, Sierra, and Lapua being popular choices among precision shooters. The cartridge is often loaded with slow-burning powders such as H4350, RL-17, or N150, which complement its modest case capacity—about 47 grains of water, as indicated by its name. Despite the relatively small cartridge size, the 6x47 SM delivers muzzle velocities in the neighborhood of 2,900 to 3,100 feet per second with standard match bullets, resulting in a characteristically flat trajectory and predictable performance at 600 meters and beyond. Other notable features are its efficient case design, which promotes long brass life and minimal neck growth, reducing the frequency of case trimming and resizing for reloaders. The 6x47 SM’s standardized chamber, universal case availability, and ease of reloading further enhance its reputation among handloaders striving for repeatable accuracy and reliable feeding, whether in single-shot competition actions or magazine-fed rifles.
