Sierra MatchKing Rifle Bullets in 6.5mm, .264 inch, 142 grain hollow point boat tail (Sierra part no. 1742MP) are built for the 6.5mm bore’s resurgence among High Power, Silhouette, and long-range competitors. Compared to Sierra’s 140-grain #1740 bullet, this 142-grain #1742 uses a longer ogive radius, giving it a higher ballistic coefficient and less sensitivity to crosswinds downrange. MatchKing bullets are built and proven for record-setting target accuracy, not for hunting.
