Sierra MatchKing Bullets MatchKings are Sierra's pre-eminent target bullets and are available in calibers from 22 through 338. All Match King bullets are designed with primary emphasis on accuracy, and game taking ability or hunting potential is not taken into consideration. MatchKing bullets have extremely thin jackets, and jacket concentricity is held to an exacting tolerance of 0.0003 maximum variation. All MatchKings have a hollow point design and a small meplat for high ballistic coefficient. MatchKing bullets have been used to win more target competitions than all other target bullets combined.
