Sierra MatchKing Features The Sierra MatchKing design has set the worldwide standard for consistent accuracy in both rifles and handguns chambering 30 caliber cartridges. This 177 grain hollow point boat tail bullet measures .308 inch in diameter and uses a closed nose meplat along with other subtle refinements over the earlier 175 grain MatchKing to push the ballistic coefficient to a .545 G1 rating. That higher BC translates directly into a flatter trajectory and reduced wind drift at extended distances which is exactly what long range competitors need when calling shots past 600 yards. The boat tail profile further stabilizes the bullet in flight delivering the superb accuracy and high momentum retention that have made MatchKing bullets the choice of record-setting shooters for decades. Because this bullet shares much of its external geometry with Sierra s proven 175 grain MatchKing reloaders can often use their existing load data and die settings as a starting point shortening the path to an accurate load. The jacketed lead core construction delivers the uniformity shot to shot that match shooters depend on whether loading for a bolt action precision rifle or a large frame handgun chambered in a 30 caliber silhouette cartridge. Sierra notes that MatchKing bullets are built for accuracy rather than hunting since their design does not guarantee the same explosive terminal expansion as the company s dedicated hunting bullets. Packaged 250 to a box the Sierra MatchKing 177 grain HPBT is available for sale at GrabAGun for serious long range and silhouette competitors.
