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. Sierra has enhanced a segment of the MatchKing line by adding the acetal resin tip, thus crowning the Tipped MatchKing (TMK) bullet line. The major advantage of adding a tip to the bullet is the reduction of drag, producing a more favorable ballistic coefficient. Due to the ballistic advantage that the tip provides, the 168 Tipped MatchKing (TMK) will stay supersonic at 1,000 yards at normal .308 Winchester velocities, unlike its untipped counterpart. The Tipped MatchKing (TMK) bullet is an excellent choice for Palma and F-Class (FTR / F Open) matches, as well as 3-Gun and various other competitions. Although the MatchKing line is recognized around the world for record setting accuracy, like their untipped counterparts, Tipped MatchKing (TMK) bullets are not recommended for hunting anything larger than varmints. This is not loaded ammunition.
