The Sierra MatchKing 303 Cal & 7.7mm Japanese 174 Gr HPBT bullets (.311 diameter) are purpose-built for precision rifle reloaders who demand match-grade accuracy on the range. Whether you're loading for a .303 British, 7.7mm Japanese, or other cartridges that chamber .311 projectiles, these hollow-point boat-tail rounds represent Sierra's long-standing commitment to tight tolerances and consistent ballistic performance. MatchKing bullets have earned their reputation among competitive shooters and serious handloaders through decades of record-setting accuracy in benchrest, F-Class, and long-range target disciplines.
What sets MatchKing bullets apart is Sierra's exacting manufacturing standard. Each bullet features a concentricity tolerance held to 0.0003 inches maximum variation, and weight is controlled to within ±0.3 grain—the kind of consistency that makes meaningful differences downrange when every shot counts. The hollow-point design incorporates a very small meplat (tip opening) optimized for high ballistic coefficient, while the boat-tail profile further reduces drag for superior ballistic performance and energy retention at distance.
These are match and target bullets, period. They're engineered for paper-punching accuracy and competitive shooting applications where precision is the only metric that matters. Sierra explicitly does not recommend MatchKing bullets for hunting—that's not their role, and trying to use them that way goes against the design intent. If you're a reloader assembling ammunition for range work, competition, or precision shooting, the 174-grain MatchKing in .311 diameter is a proven choice that will reward quality hand-loading practices with consistent, exceptional accuracy.

Frequently Asked Questions
What rifles and cartridges do these .311 diameter bullets work in?
The .311 diameter is used in .303 British, 7.7mm Japanese, and other similar cartridges that chamber .311 projectiles. Always verify that your specific cartridge and rifle are compatible before loading. Consult published reloading data for your exact firearm.
Are MatchKing bullets suitable for hunting?
No. Sierra MatchKing bullets are designed exclusively for target and competition shooting. They are not recommended for hunting applications and should be reserved for range work and precision shooting disciplines.
Why do MatchKing bullets cost more than other options?
The premium reflects Sierra's exacting manufacturing tolerances. Concentricity held to 0.0003 inches and weight variance of only ±0.3 grain are benchmark standards that directly translate to shot-to-shot consistency and accuracy on the target—qualities that matter when you're competing or pursuing precision at distance.
What makes the boat-tail design beneficial?
The boat-tail profile reduces aerodynamic drag and improves ballistic coefficient, which means better energy retention and more predictable performance at distance. Combined with the hollow-point meplat design, the boat tail is part of Sierra's formula for exceptional accuracy and ballistic performance.
