Sierra MatchKing .25 Cal 131 gr HPBT Bullets (Sierra part no. 9631) are Sierra’s flagship target bullet, engineered from the ground up for accuracy. Every MatchKing uses a thin jacket drawn to an exacting concentricity standard with weight held to within a fraction of a grain, and the hollow-point boat-tail design pairs a very small meplat with a boat-tail base for a high ballistic coefficient and minimal drag. MatchKing has a long record of setting and winning competitive accuracy records, and while some shooters use it for varmint hunting, Sierra recommends it strictly for target shooting rather than big-game hunting.
