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. The 77 grain Tipped MatchKing (TMK) allows seating to an OAL that permits cartridges to be loaded into M16/AR15 magazines.
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. Having heavier jackets than our Hornet or Blitz line of bullets, these bullets will not provide the same explosive expansion on small varmints. The #7177 was introduced in January 2015.
This bullet requires a barrel twist rate of 1x8? or faster.
