The SK Biathlon Sport cartridge is a result of innovative engineering and a long history of close co-operation with top biathletes. This biathlon ammunition combines effective and reliable energy with the finest match standard accuracy. The SK Biathlon projectile has ideal velocity for frigid conditions, and it is designed for optimum ballistic performance even in tough and windy shooting circumstances. The SK Biathlon Sport round features a special lubricant designed specifically for perfect shooting performance in freezing weather. Yet this ammo performs even in regular .22LR disciplines such as silhouette or rimfire benchrest, proving that the SK headstamp is the true sign of quality rimfire ammunition.
