Sierra enhanced select MatchKing designs by adding an acetal resin tip creating the Tipped MatchKing® (TMK) line. The addition of the tip reduces drag and delivers a higher ballistic coefficient improving downrange performance. It also promotes smooth reliable feeding in magazine-fed firearms. – Known worldwide for record-setting accuracy MatchKing® and Tipped MatchKing® bullets are engineered for target shooting and are not recommended for most hunting applications.
