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. The 175 grain 30 caliber MatchKing (#2275) was created to allow .308 Winchester shooters to stay supersonic at 1,000 yards. The popularity this advantage created made adding the 175 grain Tipped MatchKing (TMK) bullet a necessity. The 175 grain Tipped MatchKing (TMK) bullet is an excellent choice for F-Class (F Open) matches, as well as 3-Gun and various other competitions.
