5.56 77GR Bone Frog Ammunition™ Sierra Tipped MatchKing (TMK)

5.56 77GR Bone Frog Ammunition™ Sierra Tipped MatchKing (TMK)

**INAUGURAL RUN RELEASING SOON**

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
