Sierra Bullets recently announced its new MatchKing-X bullet, billing it as “the next evolution of Sierra Bullets’ MatchKing series—designed with hunters in mind.”

More from Sierra: “The MatchKing-X offers the incredible long-range accuracy and shot-to-shot consistency that shooters have come to expect from the MatchKing series, now enhanced with proven terminal performance for reliable results in the field.”

Unlike regular MatchKing bullets, the MatchKing-X features key design enhancements that allow the jacket to open and expand rapidly. A draw-and-trim method creates a significantly thinner jacket mouth, with light skives on the nose of the bullet for controlled expansion. Additionally, the MatchKing-X uses a softer lead core than the traditional MatchKing bullet, increasing its effectiveness on game.

While enhanced for terminal performance, MatchKing-X bullets are held to the same accuracy standards as their MatchKing counterparts. With identical ogives as the MatchKing, the MatchKing-X allows shooters to maintain existing trajectory data and seating depth without adjustments.

MatchKing-X bullets also maintain the original Sierra MatchKing’s weight and jacket concentricity specifications.

MatchKing-X bullets are available in these sizes: 6.5 mm/.264 142-grain, .270-cal./.277 135-grain, .30-cal./.308 175-grain and .30-cal./.308 200-grain.

“MatchKing-X is the culmination of years of consumer demand and dedicated innovation from our team. For a long time, hunters have sought to harness the unmatched ballistics performance and accuracy of the original MatchKing bullet in the field,” Sierra Bullets Marketing Manager Colby Adamek said. “However, because the original MatchKing was not engineered for reliable expansion, we could not recommend it for ethical hunting applications. Today, we’re proud to introduce MatchKing-X—a purpose-built evolution that delivers the legendary accuracy of MatchKing with the terminal performance hunters require.”

MSRP for the Sierra MatchKing-X bullet lineup ranges from $57.99 for a 100-count box of .270-cal./.277 135-grain bullets to $294.99 for a 500-count box of .30-cal./.308 200-grain bullets.
