Sierra Bullets 2240: MatchKing Bullets are Sierra\'s pre-eminent target bullets. The driving motivation for the design of each MatchKing bullet is accuracy. These bullets have very thin jackets drawn to an exacting concentricity standard of 0.0003 in maximum variation, and their weight is held to within -+0.3 grain. All MatchKing have a hollow point design with a very small meplat for high ballistic coefficient. The majority of these bullets have a boat tail shape to further minimize drag and improve ballistic coefficient. Although some of these bullets have been used for hunting, Sierra recommends them only for target shooting.
