The Sierra MatchKing .375 caliber 350 grain hollow-point boat-tail rifle bullet (Sierra part no. 9350) carries the MatchKing name that shooters worldwide have associated with accuracy and superior ballistic performance for decades. MatchKing is Sierra’s classification for its pre-eminent target bullets, built with thin jackets drawn to an exacting concentricity standard of 0.0003 inch maximum variation and weight held to within plus or minus 0.3 grain. Like the rest of the MatchKing line, this bullet uses a hollow-point design with a small meplat for a high ballistic coefficient, plus a boat-tail shape that further minimizes drag.
