When it comes to producing the best-possible match ammunition, today's precision shooters often turn to Sierra Bullets and the company's popular MatchKing lineup. Now, Sierra made its top-tier projectile even better with an all-new Tipped MatchKing (TMK) collection of bullets. Each Sierra Tipped MatchKing round is topped with a special tip made from acetal resin. This new design provides improved aerodynamic efficiency, reducing bullet drag and creating a better ballistic coefficient. The rounded profile of the projectile also enables it to feed better from a magazine. Bullet diameter: .224 inch Bullet weight: 60 grains Quantity: 100 or 500 rounds Sierra recommends that those who use their Sierra Tipped MatchKing rounds stick with target shooting or hunting animals no larger than varmints, due to the thicker jacket on these rounds.
