The Sierra MatchKing .303 caliber 174 grain Hollow Point Boat Tail (HPBT) bullet is a precision match projectile designed for consistent accuracy and reliable performance in rifles chambered for .303 British and similar cartridges. Featuring a streamlined profile with a hollow point tip and boat-tail base, it offers a high ballistic coefficient for improved stability, reduced wind drift, and enhanced long-range capability. Manufactured to tight tolerances, it is widely favored by target shooters and competitors for its uniformity and accuracy, and is intended for target shooting rather than hunting.
