Sierra Tipped MatchKing Features The Sierra Tipped MatchKing line builds on Sierra s record-setting MatchKing bullet designs by adding an acetal resin tip to the ogive reducing aerodynamic drag and raising the ballistic coefficient over the bullet s flight path. This 6mm .243 diameter bullet weighs 107 grains and posts a G1 BC of 0.574 and a G7 BC of 0.292 giving handloaders strong figures for extended-range accuracy work. The tip also smooths the bullet s profile for more reliable feeding through magazine-fed actions reducing the chance of hang-ups during rapid strings of fire. A barrel twist rate of 1:8 or faster is required to properly stabilize this bullet weight in flight. Constructed with a jacketed lead core the Tipped MatchKing is purpose-built for match and target pursuits rather than hunting applications as its construction does not provide the same controlled expansion as dedicated hunting bullets. Each box contains 500 bullets giving competitive shooters and precision handloaders a bulk supply for extended load development and practice sessions. Sierra s reputation for consistency and tight tolerances carries through the TMK line supporting repeatable accuracy from load to load. Sierra Tipped MatchKing 6mm 107 grain bullets are built for handloaders developing match-grade ammunition for serious target shooting.
