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 and thus crowning the Tipped MatchKing (TMK) bullet line. The major advantage of adding a tip to the bullet is the reduction of drag and producing a more favorable ballistic coefficient. The Tipped MatchKing (TMK) bullet is an excellent choice for Palma and F-Class (FTR / F Open) matches and as well as 3-Gun and various other competitions. Another benefit is reliable feeding in magazine fed firearms. Although the MatchKing line is recognized around the world for record setting accuracy and like their untipped counterparts and Tipped MatchKing (TMK) bullets are not recommended for hunting anything larger than varmints. Having heavier jackets than the Hornet or Blitz line of bullets and these bullets will not provide the same explosive expansion on small varmints. -This is not loaded ammunition.
