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. Another benefit is reliable feeding in magazine fed firearms. While they are recognized around the world for record-setting accuracy, MatchKing? and Tipped MatchKing? bullets are not recommended for most hunting applications. Although MatchKing? and Tipped MatchKing? bullets are commonly used for varmint hunting, their design will not provide the same reliable explosive expansion at equivalent velocities in varmints compared to their lightly jacketed Hornet, Blitz or Varminter counterparts. This bullet requires a barrel twist rate of 1?10? or faster.
