Sierra MatchKing X Features The Sierra MatchKing X is a jacketed lead hollow point boat tail bullet designed as a mirrored image of the renowned 107 grain MatchKing sharing the exact same ogive profile and external dimensions as its match counterpart. This shared geometry means reloaders who already have dies set up for the standard MatchKing can switch to the MKX for hunting applications without making any seating die adjustments. At 6mm caliber with a .243 inch diameter this bullet is engineered for reliable expansion at midrange velocities giving hunters the terminal performance they need on game while retaining match-grade accuracy. A high ballistic coefficient of 0.477 G1 means the MKX mirrors the flat predictable flight performance of its MatchKing counterpart downrange. Because the MKX shares its flight characteristics with the proven MatchKing line shooters can move between ringing steel at the range and taking game in the field without sacrificing the precision they expect from Sierra bullets. This dual-purpose design is a meaningful advantage for reloaders who want to simplify their load development rather than maintaining two completely separate recipes for match and hunting use. These are component bullets intended strictly for handloading and are not loaded ammunition giving reloaders full control over powder charge and seating depth to tune their own precision load. Available for sale at GrabAGun the Sierra MatchKing X is a strong choice for reloaders who want one bullet capable of both match and hunting performance.
