Sierra 22 Cal 77gr HPBT MatchKing

The Sierra 22 Cal 77gr HPBT MatchKing bullet component is a match-grade projectile engineered for extreme precision in AR-15/M16A2 service-rifle platforms. Featuring a hollow-point boat-tail profile and a specifically tuned ogive, this 77 grain bullet allows seating to an overall length compatible with M16/AR-15 magazines. With a required barrel twist rate of 1:8″ or faster, it offers benchrest-level accuracy and flat trajectories popular among national-level Service Rifle competitors.

Constructed with Sierra’s exacting manufacturing standards, the 22 Cal 77gr HPBT MatchKing delivers consistent weight, concentricity, and precise bearing-surface alignment—all critical for sub-MOA precision under competition conditions. The hollow-point cavity reduces meplat size for increased ballistic coefficient without compromising aerodynamics, while the boat tail assists in stabilizing flight and minimizing drag to resist wind drift.

This bullet has set numerous national records in Service Rifle competition thanks to its ability to maintain accuracy when seated to AR/M16 magazine OALs. It is available in cannelured versions (#9377G in 500-count boxes and #9377GT in 50-count boxes), offering handloaders the option to crimp securely while preserving match-level performance.

Importantly, like all Sierra MatchKing® bullets, the 22 Cal 77gr HPBT MatchKing is not recommended for hunting. Its design favors competitive accuracy over explosive terminal expansion—so hunters seeking reliable varmint terminal performance should consider lightly jacketed alternatives such as Hornet®, BlitzKing®, or Varminter® bullets.

Reloaders looking to elevate their AR-15/M16 performance will find the Sierra 22 Cal 77gr HPBT MatchKing to be an elite match component—combining magazine compatibility, precise engineering, and record-setting accuracy in a turnkey package designed for success in serious Service Rifle competition.
