The Sierra MatchKing 7mm/.284 caliber 150-grain hollow-point boat-tail rifle bullets are engineered for shooters who demand match-grade accuracy at the bench and on the range. This 500-count box delivers the precision bullet that has earned Sierra's reputation among competitive shooters and hand-loaders pursuing sub-MOA groups. Built to exacting concentricity standards and weight tolerances, MatchKing bullets are the logical choice when your reload's accuracy matters as much as your rifle does.
What sets these 150-grain projectiles apart is their obsessive attention to manufacturing consistency. Each bullet is held to a concentricity standard of 0.0003 inches maximum runout and weight variance of plus or minus 0.3 grain—tolerances that eliminate variables beyond your control. The boat-tail design minimizes drag and improves ballistic coefficient, while the hollow point with minimal meplat contributes to the high BC that keeps these bullets stable downrange. Thin jackets drawn to specification give you the precision-to-velocity relationship hand-loaders depend on for load development.
These bullets are purpose-built for accuracy-focused applications: benchrest competition, load development, and long-range target work where consistency outweighs other considerations. The 500-count packaging is practical for serious reloaders who work up loads methodically and value having a sufficient quantity to test and refine. Sierra's quality standards have made MatchKing the reference standard for what precision ammunition performance means in American shooting.

| Weight | 150 grains |

MatchKing is Sierra's designation for their premium target-grade bullets engineered for accuracy above all else. They're designed for hand-loaders, benchrest competitors, and precision rifle shooters developing loads for range use. Sierra does not recommend MatchKing bullets for hunting applications.
A 500-round quantity allows you to safely work up multiple loads, test velocity nodes, and refine your load without running out of bullets mid-development. It's the practical minimum for serious hand-loaders pursuing consistent precision ammunition.
Concentricity—the roundness and straightness of the bullet as it travels down your barrel—directly affects accuracy. Sierra holds these bullets to 0.0003 inch maximum variation, meaning the bullet stays truer in the bore, reducing the variables that cause fliers and improving your potential for tight groups.
These are match-grade target bullets. Sierra does not recommend MatchKing bullets for hunting. For hunting applications, choose ammunition or bullets designed specifically for field use.
