Sierra MatchKing rifle bullets are super-accurate bullets with very thin jackets and are held to exacting tolerances in diameter and weight. Their accuracy has been acclaimed worldwide and they have been used to win more target competitions than all target bullets from other manufacturers combined. Weight retention is held to within +/- 0.3 grain. Each bullet is a hollow point and is designed with a very small meplat in order to achieve the highest ballistic coefficient possible. The 6.5mm 120 Grain MatchKing was designed for use in medium capacity cartridges used in BenchRest and HighPower competitions out to 600 yards.
